MR. JUSTICE STONE delivered the opinion of the Court.
The National Labor Relations Board ordered respondent
affirmatively to bargain collectively with the San Antonio
Newspaper Guild, the authorized representative of respondent's
employees. In addition, it ordered respondent (1) to "cease and
desist" from refusing to bargain collectively with the Guild; (2)
to "
cease and desist' from interfering with, restraining or
coercing its employees in the exercise of their rights to
self-organization," and other rights guaranteed by § 7 of the
National Labor Relations Act, 49 Stat. 449, 29 U.S.C.Supp.V, §
151 et seq.; (3) to post notices stating, among other
things, that respondent will "cease and desist as aforesaid" and
will bargain collectively with the organized representative of its
employees. On the record before us, the question for our decision
is whether the provisions of the order which we have enumerated are
supported by the Board's finding that the respondent had refused to
bargain collectively with the authorized representative of its
employees, and had interfered with such bargaining negotiation, and
had thereby interfered with the exercise of the rights guaranteed
by § 7 of the Act.
The Board issued its complaint charging respondent, a publisher
of a newspaper, with refusal to bargain collectively with the Guild
as the authorized representative of the employees in respondent's
editorial department, and that, by such refusal and by statements
made by respondent at a meeting of those employees, it "did
interfere with, restrain and coerce" its employees in the exercise
of the rights guaranteed by § 7 of the Act,
* and did
Page 312 U. S. 429
engage in unfair labor practices defined by §§ 8(1)
and 8(5). The usual proceedings and hearings before the Board
resulted in findings by the Board to the effect that, although
respondent had throughout recognized the organization of
respondent's editorial room employees and the Guild as their
representative, and had met with the Guild representatives whenever
requested for the purpose of discussing the employees' demands, it
nevertheless had persistently refused to discuss in detail the
proposals of the Guild, to make any counterproposals, or to enter
into any agreement with it, and had not negotiated in good faith in
a genuine effort to compose the differences between employer and
employees.
The Board found that respondent had refused to bargain as
required by § 8(5) of the Act. It found that respondent had
made the statements charged in the complaint at a meeting of its
employees, and that these statements were an "interference with the
Guild's efforts to negotiate." Treating respondent's action in
refusing to bargain and in interfering with the bargaining
negotiations as an infringement of all the rights guaranteed to the
employees by the Act, it found broadly, in the words of the
statute, a violation of § 8(1), which declares that it is an
unfair labor practice for the employer "to interfere with,
restrain, or coerce employees in the exercise of the rights
guaranteed in § 7." Section 7 provides:
"Employees shall have the right to self-organization, to form,
join, or assist labor organizations, to bargain collectively
through representatives of their own choosing, and to engage in
concerted activities, for the purpose of collective bargaining or
other mutual aid or protection. "
Page 312 U. S. 430
From all this, the Board concluded that the "appropriate remedy"
was an order directing respondent, "upon request, to bargain
collectively with the . . . Guild" as the "exclusive
representative" of respondent's editorial room employees, and, "if
understandings are reached, to embody such understandings in a
signed agreement if requested to do so by the Guild." Having
provided the recommended remedy by the provisions of its order
directing the respondent to bargain and to cease and desist from
refusing to bargain, the Board went further and ordered broadly
that respondent should, in effect, refrain from violating the Act
in any manner whatsoever. This it did by paragraph 1(b) of the
order, which directed respondent to cease and desist from
"In any manner interfering with, restraining, or coercing its
employees in the exercise of their rights to self-organization, to
form, join, or assist labor organizations, to bargain collectively
through representatives of their own choosing, and to engage in
concerted activities for the purposes of collective bargaining or
other mutual aid and protection, as guaranteed in Section 7 of the
Act."
It is this and the provisions of the order other than that part
of it directing respondent to bargain which are the subjects of the
present controversy.
Upon petition of the Board to enforce the order, the Court of
Appeals for the Fifth Circuit struck from it all the provisions
except that which directed respondent to bargain with the Guild on
request, and to embody any understanding in a signed agreement. For
so much of the order as directed the posting of notices, the court
substituted a requirement that respondent notify the Guild of its
willingness to comply with the order as modified and to notify a
specified agent of the Board what steps respondent had taken to
comply with the order. 111 F.2d 588. We granted certiorari, 311
U.S. 638, the questions
Page 312 U. S. 431
raised being of importance in the administration of the National
Labor Relations Act.
Although respondent has not sought certiorari, it seeks to
retain such advantages as it may have gained from the modification
of the Board's order below by arguing broadly that the Board's
finding of respondent's refusal to bargain is without support in
the evidence, which it is said shows only that respondent refused
to yield to the Guild demands, as it was free to do. But, in the
absence of a cross-petition for certiorari by respondent, that
question is not open here. Without the findings relating to
respondent's refusal to bargain, there was no basis for any order
by the Board, and we think that the purpose and effect of the
judgment sustaining so much of the Board's order as directed that
respondent bargain with the Guild was to sustain the findings on
which it was based. This appears both from the opinion of the Court
of Appeals, the purport of which is that respondent in its
negotiations with the Guild had not acted in good faith and so had
failed to bargain as the statute requires, and also from the terms
of the judgment modifying the Board's order. The judgment affirming
the Board's order as modified retained, as the foundation of the
judgment, the recital contained in the Board's original order that
it was made upon the basis of all the Board's findings. In this
state of the record, our review is limited to the sufficiency of
the Board's findings to support the order.
We conclude also that it is not open to respondent to challenge
the judgment below, as it attempts to do, on the ground that the
Board's complaint in charging a failure to bargain did not
sufficiently inform respondent of the contention that it had failed
to bargain in good faith. This is the case both because respondent
has sought no review of the judgment below and because it
sufficiently appears from the record that, in the
Page 312 U. S. 432
course of the hearings before the Board, respondent was fully
advised of the nature of the Board's contention.
But it is the Board which has brought the judgment below here
for review, and on it rests the burden of showing in what respects
the judgment is erroneous.
Cf. Federal Trade Commission v.
Beech Nut Co., 257 U. S. 441. To
sustain that burden, the Board insists that all the provisions of
its order were lawfully made, and that it is entitled to have the
order enforced in its entirety. Section 10(c) of the Act provides
that, if the Board,
"upon all the testimony taken . . . , shall be of the opinion
that any person named in the complaint has engaged in or is
engaging in any such unfair labor practice, then the Board shall
state its findings of fact and shall issue and cause to be served
on such person an order requiring such person to cease and desist
from such unfair labor practice, and to take such affirmative
action . . . as will effectuate the policies of this Act."
The Board, having found in this case that respondent had refused
to bargain, that part of its order directing respondent to "cease
and desist from refusing to bargain collectively" with the Guild
was in exact compliance with the statute, and should have been left
undisturbed by the judgment below.
A question of a different nature is presented by Paragraph 1(b)
of the order, by which the Board, on the basis of respondent's
action in refusing to bargain and its statements interfering with
the bargaining negotiations, has directed respondent not to violate
"in any manner" the duties imposed on the employer by the statute.
Petitioner argues that, since respondent's refusal to bargain,
which is a violation of § 8(5), is also a violation of §
8(1), which in terms incorporates by reference all the rights
enumerated in § 7, the Board is not only free to restrain
violations like those which respondent has committed, but any other
unfair labor
Page 312 U. S. 433
practices of any kind which likewise infringe any of the rights
enumerated in § 7, however unrelated those practices may be to
the acts of respondent which alone emerged in course of the hearing
and which the Board has found.
But we think it does not follow that, because the acts of
respondent which the Board has found to be an unfair labor practice
defined by § 8(5) are also a technical violation of §
8(1), the Board, in the circumstances of this case, is justified in
making a blanket order restraining the employer from committing any
act in violation of the statute, however unrelated it may be to
those charged and found, or that courts are required for the
indefinite future to give effect in contempt proceedings to an
order of such breadth.
We cannot find such authority or requirement in the carefully
chosen language of § 10(c), which directs the Board to state
its findings of fact showing the unfair labor practice charged and
to order the person accused to "cease and desist from such unfair
labor practice," or in § 10(e) of the Act, which authorizes
the court, on application of the Board, to enter a "decree
enforcing, modifying, and enforcing as so modified, or setting
aside in whole or in part the order of the Board." It is obvious
that the order of the Board, which, when judicially confirmed, the
courts may be called on to enforce by contempt proceedings, must,
like the injunction order of a court, state with reasonable
specificity the acts which the respondent is to do or refrain from
doing. It would seem equally clear that the authority conferred on
the Board to restrain the practice which it has found the employer
to have committed is not an authority to restrain generally all
other unlawful practices which it has neither found to have been
pursued not persuasively to be related to the proven unlawful
conduct.
Page 312 U. S. 434
Congress has itself afforded a guide pointing to the appropriate
limits of the order which the Board is to make in restraining
unfair labor practices. By its definition and classification of
unfair labor practices in the statute, it has shown that they are
not always so similar or related that the commission of one
necessarily merits or rightly admits of an order restraining all.
Here, the whole controversy between respondent and the Guild was
with respect to the Guild's requests to bargain and respondent's
attempt to influence the negotiations and its ultimate refusal to
enter into an agreement, from all of which the Board inferred the
refusal to bargain in good faith. In all other respects, respondent
has consistently left the Guild and its activities undisturbed. The
Board made no finding, and there is nothing in the record to
suggest, that the failure of the bargaining negotiations and all
that attended them gave any indication that, in the future,
respondent would engage in all or any of the numerous other unfair
labor practices defined by the Act.
Refusal to bargain, defined as an unfair labor practice by
§ 8(5), may be, as we think it was here, wholly unrelated to
the domination of a labor union or the interference with its
formation or administration or financial or other support to it,
all of which are defined as unfair labor practices by § 8(2).
Refusal to bargain may be, as we think it was here, wholly
unrelated to
"discrimination in regard to hire or tenure of employment or any
term or condition of employment to encourage or discourage
membership in any labor organization,"
all of which are unfair labor practices as defined by §
8(3). Here, the Board made no finding, based either on the specific
circumstances disclosed by the record or on its own expert judgment
of their relation to the policy embodied in § 7, or as to any
relationship or probable relationship of respondent's refusal to
bargain and the other types of unfair practices some of which are
enumerated
Page 312 U. S. 435
in § 8. Yet, if the contention which it makes is to be
sustained, subsequent violations of § 8(2) and (3) which are
also violations of § 8(1) may be the subject of a contempt
order merely because respondent, by the refusal to bargain, has
violated § 8(5), which is similarly a violation of §
8(1).
In view of the authority given to the Board by § 10(c),
carefully restricted to the restraint of such unfair labor
practices as the Board has found the employer to have committed,
and of the broad language of § 10(e) authorizing the courts to
modify the order of the Board wholly or in part, we can hardly
suppose that Congress intended that the Board should make, or the
court should enforce, orders which could not appropriately be made
in judicial proceedings. This is the more so because § 10(a),
which authorizes the Board "as hereinafter provided, to prevent any
person from engaging in any unfair labor practice," specifically
directs that
"This power shall be exclusive, and shall not be affected by any
other means of adjustment or prevention that has been or may be
established by agreement, code, law, or otherwise."
In the light of these provisions, we think that Congress did not
contemplate that the courts should, by contempt proceedings, try
alleged violations of the National Labor Relations Act not in
controversy and not found by the Board and which are not similar or
fairly related to the unfair labor practice which the Board has
found.
A federal court has broad power to restrain acts which are of
the same type or class as unlawful acts which the court has found
to have been committed or whose commission in the future unless
enjoined, may fairly be anticipated from the defendant's conduct in
the past. But the mere fact that a court has found that a defendant
has committed an act in violation of a statute does not justify an
injunction broadly to obey the statute, and thus subject the
defendant to contempt proceedings if
Page 312 U. S. 436
he shall at any time in the future commit some new violation
unlike and unrelated to that with which he was originally charged.
This Court will strike from an injunction decree restraints upon
the commission of unlawful acts which are thus dissociated from
those which a defendant has committed.
Swift & Co. v.
United States, 196 U. S. 375;
New York, New Haven & Hartford R. Co. v. Interstate
Commerce Commission, 200 U. S. 361,
200 U. S. 404,
and see, under the National Labor Relations Act,
Labor
Board v. Swift & Co., 108 F.2d 988.
It is a salutary principle that, when one has been found to have
committed acts in violation of a law, he may be restrained from
committing other related unlawful acts. But we think that, without
sacrifice of that principle, the National Labor Relations Act does
not contemplate that an employer who has unlawfully refused to
bargain with his employees shall, for the indefinite future,
conduct his labor relations at the peril of a summons for contempt
on the Board's allegation, for example, that he has discriminated
against a labor union in the discharge of an employee, or because
his supervisory employees have advised other employees not to join
a union.
See, e.g., H. J. Heinz Co. v. Labor Board,
311 U. S. 514.
Having found the acts which constitute the unfair labor
practice, the Board is free to restrain the practice and other like
or related unlawful acts. But, as the Court has held in the case of
the Federal Trade Commission,
see Federal Trade Commission v.
Beech Nut Co., supra,
257 U. S. 455, an order not so related should be
appropriately restricted on review. The breadth of the order, like
the injunction of a court, must depend upon the circumstances of
each case, the purpose being to prevent violations the threat of
which in the future is indicated because of their similarity or
relation to those unlawful acts which the Board has found to have
been committed
Page 312 U. S. 437
by the employer in the past.
See United States v.
Trans-Missouri Freight Assn., 166 U.
S. 290,
166 U. S.
308-309;
Standard Oil Co. v. United States,
221 U. S. 1,
221 U. S. 77;
Texas & New Orleans R. Co. v. Brotherhood of Railway
Clerks, 281 U. S. 548;
Local 167 v. United States, 291 U.
S. 293;
Virginian Railway Co. v. System Federation
No. 40, 300 U. S. 515,
300 U. S.
541-544. We hold only that the National Labor Relations
Act does not give the Board an authority, which courts cannot
rightly exercise, to enjoin violations of all the provisions of the
statute merely because the violation of one has been found. To
justify an order restraining other violations, it must appear that
they bear some resemblance to that which the employer has
committed, or that danger of their commission in the future is to
be anticipated from the course of his conduct in the past. That
justification is lacking here. To require it is no more onerous or
embarrassing to the Board than to a court. And, since we are in a
field where subtleties of conduct may play no small part, it is
appropriate to add that an order of the Board, like the injunction
of a court, is not to be evaded by indirections or formal
observances which in fact defy it. After an order to bargain
collectively in good faith, for example, discriminatory discharge
of union members may so affect the bargaining process as to
establish a violation of the order.
The Board places strong reliance on
Labor Board v. Fansteel
Metallurgical Corp., 306 U. S. 240, and
on
Texas & New Orleans R. Co. v. Brotherhood of Railway
Clerks, supra, 281 U. S. 555,
281 U. S.
567-571, and
Virginian Ry. Co. v. System Federation
No. 40, supra, 300 U. S. 543,
300 U. S. 544.
In those cases, the cease and desist order and the injunctions were
substantially like paragraph 1(b) of the Board's order in the
present case. But, in them, the unfair labor practices did not
appear to be isolated acts in violation of the right of
self-organization, like the refusal
Page 312 U. S. 438
to bargain here, but the record disclosed persistent attempts by
varying methods to interfere with the right of self-organization in
circumstances from which the Board or the court found or could have
found the threat of continuing and varying efforts to attain the
same end in the future.
An appropriate order in the circumstances of the present case
would go no further than to restrain respondent from any refusal to
bargain and from any other acts in any manner interfering with the
Guild's efforts to negotiate. So far as respondent's past conduct
may be thought to have had any effect on the rights guaranteed by
§ 7, such consequences would be effectively prevented by the
prohibition of such an order without drawing it so broadly as to
forbid all other unrelated unfair labor practices.
Only a word need be said of that part of the Board's order
requiring the posting of notices. We have often held that the
posting of notices advising the employees of the Board's order and
announcing the readiness of the employer to obey it is within the
authority conferred on the Board by § 10(c) of the Act "to
take such affirmative action . . . as will effectuate the policies"
of the Act.
See Labor Board v. Pennsylvania Greyhound
Lines, 303 U. S. 261,
303 U. S. 268;
H. J. Heinz Co. v. Labor Board, supra.
But respondent argues that the authority of the Board does not
extend to the requirement, such as was made in this case, that the
employer confess violation of the Act by a published announcement
that he will "cease and desist" from violating it.
See Labor
Board v. Abell Co., 97 F.2d 951;
Burlington Co. v. Labor
Board, 104 F.2d 736;
Swift & Co. v. Labor Board,
106 F.2d 87;
Art Metals Construction Co. v. Labor Board,
110 F.2d 148, 151, 152;
Hartsell Mills Co. v. National
Page 312 U. S. 439
Labor Relations Board, 111 F.2d 291, 293. Since the
Board has changed its practice, and now provides in all orders that
the employers' notices shall state "that he will not engage in the
conduct from which he is ordered to cease and desist," it consents
that the present order be modified accordingly.
What we have said requires a reversal of the judgment below and
the reestablishment of the Board's order with the following
exceptions:
Paragraph 1(b) of the order will be modified so as to require
only that respondent shall cease and desist from "In any manner
interfering with the efforts of the Guild to bargain collectively
with Express Publishing Company, San Antonio, Texas."
Paragraph 2(b) of the order will be modified by striking from it
the words: "will cease and desist as aforesaid" and substituting
for them the words "will not engage in the conduct from which it is
ordered to cease and desist as aforesaid."
Reversed.
* The statements alleged to have been made by officers or agents
of respondent were, "Existing independent employment relations may
be continued by the individual employees or by employees as a
group." "No one can compel you to join any organization." And,
referring to respondent's treatment of its employees, it was
alleged that respondent's officer stated: "Each of you knows we
were not forced to do this by any labor organization, and no labor
organization can force us to do these things."
MR. JUSTICE DOUGLAS:
I think the cease and desist order should be enforced in
full.
Respondent did not object in its answer to the Board's petition
before the Circuit Court of Appeals to that portion of the Board's
order which the Court now modifies. So far as the briefs disclose,
it did not make any such objection in the Circuit Court of Appeals.
Nor did respondent question the propriety of that provision of the
order, or challenge the power of the Board to make it either in its
brief or in its oral argument here. Any controversy on that issue
before this Court is therefore not attributable to respondent. For,
on the record before us,
Page 312 U. S. 440
it must be assumed that respondent wholly acquiesces in that
phase of the Board's action. In that posture of the case, it is
plain that this Court will not customarily raise
sua
sponte objections which respondent did not choose to make. We
are, of course, asked to enforce an order of the Board. And I
suppose we might refuse to enforce provisions of such an order
which are patently
ultra vires, even though the other
party raises no objection, but acquiesces in them. But, in my view,
this provision of the order is not beyond the power of the
Board.
The order, as modified, restrains respondent from interfering in
any manner "with the efforts of the Guild to bargain collectively"
with it. But respondent is not restrained from interfering with the
employees in the exercise of their rights (a) to self-organization,
(b) to form, join, or assist labor organizations, or (c) to engage
in concerted activities for the purposes of collective bargaining
or other mutual aid and protection. These deletions represent the
loss of substantial sanctions -- sanctions which the expert
administrative agency may well have concluded are basic and
essential for protection of the right which this very union has
won.
Take the case where an employer is playing ducks and drakes with
the National Labor Relations Act. He pays mere lip service to the
requirements of the Act, while intent on blocking in his plant any
effective union action. If that is a faithful representation of his
attitude, the mandate of the Act might be wholly frustrated, or its
enforcement needlessly delayed were the Board merely to order him
to cease and desist from interfering "with the efforts" of the
union "to bargain collectively." That, without more, might well be
wholly ineffective, or so the Board in its discretion might
conclude. In fact, it might even be an open invitation to an
employer intent on evasion of the spirit and letter of the Act to
resort to devious routes to the same end. Employees are dropped --
perhaps
Page 312 U. S. 441
the leaders of the union; labor spies are employed; a company
union is sponsored and financed; new employees are selected who
promise not to join the outside union. The purpose is to thwart any
effective action by that union. Such obstructive tactics could go
on apace, and yet no "efforts" of the union "to bargain
collectively" need be denied. The employee could continue the
so-called negotiations with the union, perhaps reach at least a
tentative agreement with it, and yet in a myriad of ways undermine
it if the breadth of the cease and desist order were delimited.
Perhaps this is to conjure up remote and hypothetical
situations. Perhaps that is not this case. [
Footnote 1] But I think it is important to remind that
we do not sit as an administrative agency with discretion to adjust
the remedies accorded by the Act to what we think are the needs of
particular cases, with power to write or rewrite administrative
orders in light of what we think are the exigencies of specific
situations, with the duty to pass on the wisdom of administrative
policies. Congress has invested the Board, not us, with discretion
to choose and select the remedies necessary or appropriate for the
evil at hand.
The Board concluded (so we must presume) that its order
directing respondent to bargain collectively with the Guild need be
buttressed by broad protective provisions good against any and all
methods of evasion. Formal recitals could hardly make that plainer
than it is. [
Footnote 2] And
clearly those provisions are no broader than
Page 312 U. S. 442
the wide reaches of the controversy disclosed in this
record.
Whether the remedy chosen by the Board was reasonably necessary
in this case is not for us to determine. Nor it is for us to say
what language is adequate to safeguard the labor rights which are
in issue. To cut down the language of this order not only
substitutes our judgment for that of the Board; it will also result
in the creation of a host of uncertainties. The original order
makes clear that any attempted evasion, no matter how devious, is
banned. As modified, the order clearly subtracts from those
sanctions. But the precise extent of its dilution remains
uncertain. The Board may, of course, in case of future violations,
institute new administrative proceedings. Yet the method here
chosen for settlement of this labor controversy does not promise
peace. It invites a prolongation of the dispute which should be
deemed to have been settled, with the employer's acquiescence, once
and for all. That practical aspect of the matter is of great
importance on the merits, and it also emphasizes the seriousness of
our intrusion into the administrative domain.
See Note
(1940) 53 Harv.L.Rev. 472.
MR. JUSTICE BLACK and MR. JUSTICE REED join in this opinion.
[
Footnote 1]
It should, however, be noted that the Board concluded that "the
respondent had no intention of negotiating in good faith with the
Guild, nor of entering into a collective bargaining agreement with
it." And the Circuit Court of Appeals observed, " . . . we think
there was evidence to support the finding of the Board that
respondent had determined in advance never to agree to
anything."
[
Footnote 2]
In this connection, it should be observed that the Board found
that respondent had "interfered with, restrained, and coerced its
employees in the exercise of the rights guaranteed in Section 7 of
the Act" by reading to them a statement which "presented a
distorted concept" of the employees' rights under the Act. The
Circuit Court of Appeals set aside that finding. While the Board
did not raise that issue in its petition for certiorari, that
episode is nevertheless relevant to the scope of the cease and
desist order. If it be assumed, as does the majority, that such a
broad order must be founded at least on some evidence that other
related unlawful acts "may fairly be anticipated from the
defendant's conduct in the past," that episode is of significance.
For, though it might not of itself support an additional finding of
a separate violation of § 8, it certainly is some evidence for
the exercise of the Board's expert judgment that the refusal to
bargain did not have an improbable relationship to other likely
obstructive tactics of a related order.
