This сase requires a decision upon the sole issue of whether the owner of a shopping center may enjoin as trespass a union’s peaceful picketing of premises leased by an employer from the owner of the shopping center. As *768 we shall explain, we have concludеd that such owner is not entitled to enjoin the union from so picketing.
Plaintiff owns and operates a shopping center located on a 6-acre parcel of land leased from the City of Torrance. The shopping center consists of a parking lot, driveways, sidewalks, and several stores. Plaintiff subleases the stores to various tenants, but retains exclusive control over the parking lot and the sidewalks, including those sidewalks adjacent to the subleased stores. Tom Revels, the owner of Tom Revels Bakery, leases a store in plaintiff’s shopping center for a monthly rental of $450 plus 5 per cent of the gross income of the bakery.
Defendant union sought unsuccessfully to organize the four or five employees of the Tom Revels Bakery and towards that end began on February 16, 1962, to engage in picketing in front of the bakery on the sidewalks belonging to the plaintiff. The pickets carried signs stating that, “Revels Bakery is nonunion and is unfair to organized labor. Please do not patronize. Bakers Union Local 31.”
Plaintiff initiated this action to enjoin defendant from trespassing on plaintiff’s property. After trial the superior court entered judgment enjoining defendant and its members from entering plaintiff’s propеrty for the purpose of picketing. Defendant appeals from that judgment.
The problem presented in this ease is one of accommodating conflicting interests: plaintiff’s assertion of its right to the exclusive use of the shopping center premises to which the public in general has been invitеd as against the union’s right of communication of its position which, it asserts, rests upon public policy and constitutional protection. Resolution turns upon a balancing of the union’s interest in such peaceful picketing for a lawful purpose 1 against the plaintiff’s interest in the possession and enjоyment of his property in these special circumstances.
We turn first to an analysis of the interests of the union.
Picketing by a labor union constitutes an integral component of the process of collective bargaining; as such it *769 involves the exercise of a right which is both statutorily and constitutionally sanctioned.
The Legislature has expressly declared that the public policy of California favors concerted activities of employees for the purpose of collective bargaining or other mutual aid or protection. (Lab. Code, § 923; see
Messner
v.
Journeymen Barbers etc. International Union
(1960)
The picketing, indeed, involves an exercise of the constitutionally protected right of freedom of speech. In

Alabama

Although the court subsequently qualified its broad ruling in
ThornMll
by adopting a test permitting states to enjoin peaceful picketing for a purpose antithetical to some valid state policy,

the bedrock principle of
ThornMll,
that picketing constitutes a manifestation of free speech, remains intact.

This court has frequently acknowledged and applied the
ThornMll
principle. Thus in

v.

Nor is the union’s interest in picketing diminished because it may communicate its message at other, admittedly less advantageous, locations off plaintiff’s premises. As we said in
Wollam
v.
City of Palm Springs
(1963)
On the other hand, the countervailing interest which plaintiff endeavors to vindicate emanates from the exclusive possession and enjoyment of private property. Because of the public character of the shopping center, however, the impairment of plaintiff’s interest must be largely theoreticаl. Plaintiff has fully opened his property to the public. Approximately 10,000 people visit the premises weekly. The shopping center affords unrestricted access between its parking lot and the public streets. The center constitutes a conglomeration of business enterprises designed tо provide essential services to all members of the local community; “access by the public is the very reason for its existence.”
(Lombard
v.
United States
(1963)
Plaintiff suffers no significant harm in the deprivation of absolute power to prohibit peaceful picketing upon property to which it has invited the entire publiс. As we observed in
In re Zerbe
(1964)
*772 We cоnclude that the defendant’s interest in picketing outweighs plaintiff’s interest in vindicating a theoretical invasion of its right to exclusive control and possession of private property.
This conclusion accords with the still exiguous body of cases relating to the rights of picketers on the premises of shopping centers. A few states have adjudicated eases substantially similar to the instant one. In
Amalgamated Clothing Workers of America
v.
Wonderland Shopping Center, Inc.
(1963)
In
State
v.
Williams
(Balt.Crim.Ct. Md. 1959) 44 LRRM 2357, the court reversed defendant’s conviction of criminal trepass on the premises of a shopping center posted against peddlers, solicitors, and pickets, stating: “By opening it to the public, the owner’s property rights have become secondary to broad use by the public, which includes the right of a labor union to engage in peaceful picketing.”

at p. 2360.) Similarly, in

v.
Barisi
(N.Y.Mag.Ct. 1948) 23 LRRM

2190, involving picketing against a news company which leased space in the privately owned Pennsylvania Station, the court concluded that: “. . . by opening up their place to the general public, the owners of the station have made it a quasi-public place, and as such their ownership is ‘circumscribed by the constitutional rights of those who use it.’ ”

Although plaintiff admits that the proper resolution of this case must be found in аn accommodation of conflicting interests, it contends that precedent from this and other jurisdictions supports its position.
Plaintiff refers first to

Plaintiff further contends that the weight of authority from other states subordinates the union’s interest to the interest of the property owner. Plaintiff cites several cases, none of which support its contention.
Stafford
v.
Hood
(Tеnn.Ct.App. 1963) 53 LRRM 2771, involved trespass on the parking lot of a grocery store, not a shopping center. In
People
v.

(1961)
Plaintiff finally contends that
N.L.R.B.
v.
Babcock & Wilcox Co.
(1956)
We conclude that the picketing in the present case cannot be adjudged in the terms of absolute property rights; it must be considered as part of the law of labor relations, and a balance cast between the opposing interests of the union and the lessor of the shopping center. The prohibition of the picketing would in substance deprive the union of the opportunity to conduct its picketing at the most effective point of persuasion: thе place of the involved business. The interest of the union thus rests upon the solid substance of public policy and constitutional right; the interest of the plaintiff lies in *775 the shadow cast by a property right worn thin by public usage.
In the light of this conclusion we need not consider defendant’s contention that jurisdiction tо intervene in this dispute resides exclusively in the National Labor Relations Board. (See
In re Zerbe
(1964)
The judgment is reversed.
Gibson, C. J., Traynor, J., Sehauer, J., MeComb, J., Peters, J., and Peek, J., concurred.

Plaintiff does not, nor could it, contend that the purpose of the picketing in the instant case was unlawful. (See

Justice Cardozo has eloquently developed the thesis that “property rights” no longer enjoy the characteristic of absolutism formerly accorded them; “Property like liberty, though immune under the Constitution from destruction, is not immune from regulation essential for the cоmmon good. What the regulation shall be, every generation must work out for itself. The generation which gave us

In an. excellent analysis o£ the entire problem of peaceful picketing at shopping centers, the note-writer in Shopping Centers and Labor Relations Law (1958) 10 Stаn.L.Rev. 694, 697, points out, "There is language in the Nahas case which suggests that the landlord could prohibit the union activity. In fact, the court’s reasoning would compel such a result. Since possession and dominion over the area remained in *774 the landlord, he could maintain a trespass action.” The note suggests that such reasoning leads to the result that the success of the suit would depend upon who happened to bring it.
