The question for determination on this appeal involves the right of organized labor to strike, picket, and engage in other concerted labor activities against a governmental, rather than a private, employer.
The action was brought by the city of Los Angeles and its department of water and power, which was engaged in construction and modification work upon some eight major water and electrical projects in the city, to enjoin a group of labor unions from striking, picketing, declaring the department unfair, and engaging in other concerted action for the purpose of coercing the department to comply with certain demands of defendants regarding working conditions on said projects. A preliminary injunction was granted on March 11, 1948, after a hearing of an order to show causp issued on plaintiffs’ verified complaint. The appeal is from the injunction, and challenges its validity solely upon constitutional grounds.
By the terms of the preliminary injunction, the defendant unions, and “all persons in active concert or participation with them,” were restrained during the pendency of the action or until the further order of the court from “Striking, or calling or inducing a strike against the Department of Water and Power of The City of Los Angeles at any of its projects hereinafter enumerated, or picketing any of said projects, or giving any notice stating or implying that a strike exists at any of said projects or threatening to strike or picket any of said projects or hindering, delaying or interfering with, in any manner or by any means or device, the work upon any of said projects, for the purpose of intimidating or coercing The City of Los Angeles, the Department of Water and Power, the Board of Water and Power Commissioners, the Board of Civil Service Commissioners, or any officer of said City in the-performance of their or his lawful duties; and coercing, compelling, inducing or encouraging the employees of said Department of Water and Power, who are employed on said projects, to hinder, delay or interfere with the work on said projects, by strike, walk-out, cessation of work, or otherwise.” After describing the projects affected, *39 the injunction concluded with the statement that “Nothing in this order shall be construed as affecting the right of any employee of said Department to abandon or to resign his employment. ’ ’
The evidence upon which the injunction was granted was contained in plaintiffs’ verified complaint, and in three affidavits filed by defendants.
The following facts were before the court: The Department of Water and Power of The City of Los Angeles is a duly constituted department of the city government. It is required and empowered by the city charter to construct and operate facilities to supply water and electricity to the city and its inhabitants. Approximately $450,000,000 is presently invested in publicly owned water and electric systems under its management and control. In December, 1947, in order to meet the greatly increasing demands being made upon it by reason of the rapid growth of the city, the department was engaged in an extensive construction program to enlarge and improve its facilities. The estimated cost of the eight separate construction projects here involved exceeds $48,000,000. Of these projects, all but two were being built entirely by direct employment and purchase of materials by the department; the two largest projects were being constructed in part by independent contractors. Some 420 persons were directly employed by the department on the several projects, all of whom were classified members of the civil service. Ninety or more of these employees, and nearly all of the employees of the independent contractors, were members of one or more of defendant unions.
Beginning in December, 1947, defendant unions made repeated demands upon the department relating to working conditions. According to the allegations of the complaint, the foremost demand was “that said department require all of said persons so employed directly by it to be or become members of some one of the defendants labor unions, or that the department remove said persons from said projects and employ thereon only members of such a labor union.” Other demands alleged were as follows: That the board of water and power commissioners and board of civil service commissioners fix and classify the duties of civil service positions in the department in conformity with the craft jurisdictions and job classifications recognized by defendants; that the department provide craft foremen to supervise the work “in conformity with the provisions of the collective bargaining agreements *40 which said defendants have made with private employers ’ ’; and that the board of water and power commissioners fix wages and salaries in accordance with “standards and rules established, approved and recognized by said defendants.” Defendants’ version of the union demands, as shown by affidavit was that the unions proposed that the department follow a “union policy” on the new construction, by transferring sufficient union employees from repair and maintenance work to the new construction so as to completely man those jobs, and with respect to new employees put only union members on new construction work. Defendants admitted, by affidavit, the other demands allegedly made, and averred in justification therefor that the prevailing system of classification and definition of the duties of department employees was being used as a device to avoid payment of wages equivalent to those being paid for comparable services rendered to private employers, in violation of section 425 of the city charter. After a series of conferences between union and departmental officials, as a result of which the department allegedly made some changes in its overtime pay policies but otherwise rejected the union demands, a strike was called on February 6, 1948. The department’s projects were declared to be “unfair,” pickets were posted, and all of the union employees withdrew from work. It is not contended that the picketing was not entirely peaceful, nor that the representations made were either false or fraudulent.
The case presents the important question whether organized labor may legitimately strike and picket government itself. The city tacitly concedes that the complaint would not state a cause of action as against an ordinary employer in private industry

Retail Auto S. L. Union No. 1067,
Although no case has been found, nor has any been cited to us, which affirms that there exists a constitutional right to strike, as distinct from other constitutional rights, we are faced with a clear constitutional issue in respect to the portions of the injunction which restrain picketing and other forms of communication relating to the controversy between the parties. In
Thornhill
v.
Alabama,
The issues for decision involve public employment. At the outset we may put to one side the authorities dealing with the legality of labor objectives in disputes with private industry, as not being appropriate to our inquiry; for, as was pointedly said in
Perez
v.
Board of Police Commrs.,
The charter of the city of Los Angeles created the department of water and power as a department of the “city government,” with the power and duty, among other things, “to construct, operate, maintain, extend, manage and control works and property for the purpose of supplying the city and its inhabitants with water and electric energy. . . . ” (Charter, §§ 70, 221; Stats. 1925, pp. 1056, 1095.) Control and management of the department is vested in a board of water and power commissioners, whose members are officers of the city. (Charter, §§71, 78, 5; Stats. 1925, pp. 1056, 1058, 1039.) The board is charged with the duty to “create the necessary positions in said department, authorize the necessary deputies, assistants and employees and fix their salaries and duties, and fix the salary of the general manager of the department and may require bonds of any or all such employees for the faithful performance of their duties.” (Charter, § 86; Stats. 1925, p. 1060.) In fixing the compensation of city employees, it is provided that the appropriate authority “shall, in each instance, provide a salary or wage at least equal to the prevailing salary or wage, for the same quality of service rendered to private persons, firms or corporations under similar employment, in ease such prevailing salary or wage can be ascertained. ’ ’ (Charter, § 425, as amended; Stats. 1935, p. 2339.)
The charter further provides for a complete scheme of civil service, under the control and direction of a board of civil service commissioners, which, among other things, is charged with the duty of classifying all nonexempted positions in the city employ (including all but the highest executive positions *44 in the department of water and power). The charter requires that 11 Bach class shall include all positions sufficiently similar in respect to the duties and responsibilities therefor in which: (a) The same requirements as to education, experience, knowledge and ability are demanded of incumbents; (b) the same tests of fitness may be used in choosing qualified appointees; (c) the same schedule of compensation may be made to apply with equity. The offices and places so classified by the Board shall constitute the classified civil service of said city; and no appointment to any such offices and places shall be made except under and according to the rules hereinafter mentioned.” (Charter, §§ 100, 103; Stats. 1925, p. 1062.) Selection, appointment, and promotion of employees in the classified service is upon the basis of competitive examinations. The charter also provides that “unskilled laborers, including drivers,” and “persons employed on the construction of public works, improvements or buildings,” may be exempted from the civil service requirements “upon the request of the head of the department in which they are employed, by order of the Board of Civil Service Commissioners, approved by the [City] Council by resolution”; but “ [a]ny exemption thus made may be terminated at any time by resolution of the Board of Civil Service Commissioners. ’ ’ (Charter, § 111; Stats. 1925, p. 1066.)
The employer-employee relationship in the city’s service is governed by statutory law and administrative regulation; it is not fixed, either in whole or in part, by contract, as in the field of private industry. The positions which are “necessary” in the department of water and power must be determined by the managing board and there is no requirement that the number or nature of the positions or the required duties or skills conform to those generally established in comparable private enterprise. The board of civil service commissioners is not only free, but is under a duty to prescribe positions and classes which, in its view, most nearly accord with the letter and spirit of the civil service law. To be sure, the salaries or wages of city employees must be set at the prevailing rate, but only “in case such prevailing salary or wage can be ascertained.” To the extent that the job classifications differ, so too will the wage and salary schedules differ, as between public and private employees; and any lack of uniformity of wage policies as between private employers in comparable enterprises will normally be reflected in the determination of what is the prevailing wage for civil *45 service purposes. The provisions for open and competitive examinations as the basis of employment in the classified service rule out any discriminations in hiring policies in favor of labor union members, and, perforce, forbid a closed or union shop.
Manifestly, the operations of the department of water and power are controlled by the same public law from which its authority to act is derived. In
Nutter
v.
City of Santa Monica,
Defendants make the contention that when acting in a proprietary capacity, as the Los Angeles Department of Water and Power is asserted to be acting, the city is subject to the same obligations and liabilities as a private employer, and accordingly the availability to it of injunctive relief against strikes and picketing is the same as that of a private employer. We need not decide whether, in view of the fact that water and electricity are used by both public and private consumers, the department is acting solely in a proprietary capacity (compare
City of Huntingburg [Huntington]
v.
Morgen,
From what has already been said, we think it is self-evident that defendants may not, consistently with the public policy expressed in the Los Angeles City Charter, lawfully either strike or picket for the purpose of enforcing demands as to conditions of employment in respect to which neither the city nor the department of water and power is obligated to bargain collectively. To hold to the contrary would be to sanction government by contract instead of government by law. The charter mandate for nondiseriminatory competitive civil service examinations clearly cannot be modified by agreement, whether coerced by economic and moral suasion, or free and voluntary. Likewise, to the extent that the conditions
*47
of employment commonly arranged by contract are covered by the provisions of the city charter, those provisions are controlling and neither the board of water and power commissioners nor any other city officers, may deviate therefrom by contract. Furthermore, to the extent that the city authorities are vested by the charter with continuing discretionary powers such as the power to establish, classify (or exempt from the requirements of the classified service), and fix salaries for the various positions in the public employ, and direct the conduct of the work, such discretion may not be lawfully abdicated or delegated. (See
Mugford
v.
Mayor & City Council of Baltimore,
We may add that although the exact question of the validity of strikes and picketing against a governmental employer does not appear to have been squarely decided in any reported decision of a court of last resort, the eases uniformly recognize the validity of the principles of law which we have stated. (See
Miami Water Works Local No. 654
v.
City of Miami,
Our conclusion in this respect finds support also in numerous cases sustaining the validity of regulations prescribing, as a condition of public employment, certain restrictions upon rights which such employees would otherwise be free to enjoy as private citizens. (See
Perez
v.
Board of Police Commrs., supra; King
v.
Priest,
Defendants refer to the legislative history of Senate Bill 949 (1947 Legislature), which would have declared a strike of public employees to be contrary to public policy, and a misdemeanor. It was passed in the Senate, but no action upon it was taken by the Assembly. Under these circumstances, the failure of the Legislature to enact this proposed legislation cannot be considered as even remotely supporting defendants’ position. Its passage in the Senate would, if anything, tend to support the views we have expressed; whereas mere nonaction in the Assembly conveys no implication either way. The point is obviously untenable.
We find no merit in defendants’ further claim that the injunctive relief granted is too broad. Reasonably construed, the plain meaning of the language employed merely
*50
restrains the defendant unions from conduct we have held to be unlawful, namely, striking, picketing, and like activities where the purpose is to intimidate or coerce the city authorities in the performance of their lawful ■ duties and inducing the employees of the department of water and power to strike 'or otherwise interfere with the work on the department’s specified projects. No restraints are imposed upon the exercise, by defendants, of any other means at their disposal to publicize their grievances in an attempt to either change the 1-aw governing the conditions of employment, or convince the appropriate officers with discretionary powers of the merits of their contentions so that they might exercise their discretion favorably to defendants within the prescribed limits of their authority. In the, absence of any evidence whatsoever in the record as to the existence of a labor dispute between any of the independent contractors and its employees, we cannot assume that the injunction was intended, or would be construed to ban strikes or peaceful picketing by such private employees to enforce legitimate demands against their employers. On its face, the order only forbids action against the city. Only insofar as the employees of the contractors might engage in the specified activities in order to coerce or intimidate the officers of the city, or to induce the employees of the city to strike or cease work, would their conduct be unlawful. As has been often stated, it is “impossible to define comprehensively or with exactness each and every act which may or may not be legally done in carrying on a labor controversy; and it is evident that any attempt to do so would lead into a field of unlimited speculation.”
