OPINION
This is аn appeal from a grant of summary judgment to Teamsters Local 959 in a trespass action brought by Brown Jug, Inc. Brown Jug charged that members of Local 959 trespassed on Brown Jug's property while engaged in consumer boycott picketing at its Wasilla outlet. Local 959’s mo *934 tion for summary judgment was based on claims that state court jurisdiction is preempted by the National Labor Relations Act, and that the union should not be held liable since Brown Jug suffered no compen-sable damage and was unable to identify the individuals who allegedly trespassed. We reverse and remand.
I. FACTUAL AND PROCEDURAL BACKGROUND
As part of its strike against Anchorage Cold Storage, Local 959 of the International Brotherhood of Teamsters established consumer boycott picketing in front of stores in the Anchorage and Palmer/Wasil-la areas which carried products distributed by Anchorage Cold Storage. The pickets carried signs requesting that consumers not buy certain brands of soft drinks and alcohol. The strikers were instructed to picket peacefully, to remain on public sidewalks if store owners denied them permission to walk immediately in front of stores, and to refrain from interfering with employees of the stores or deliveries to them.
Among the stores selected by Local 959 for picketing was the Brown Jug store in Wasilla, located near the intersection of the Parks and the Palmer-Wasilla Highways. In February 1982, before the picketing began, Local 959’s business agent sent a letter to Brown Jug, advising it that the Was-illa store would be picketed. Brown Jug’s attorney contacted the business agent, and informed him that Brown Jug wanted picketers to limit their picketing to the Parks Highway and to refrain from parking in Brown Jug’s parking lot. The business representative agreed that picketers would only picket on the one hundred foot public right-of-way adjacent to the highway, that no picketing would take place in the Brown Jug parking lot or on other private property, that picketers would not park their cars in the parking lot, and that customer and emрloyee access to the store would not be restricted.
Brown Jug alleges (and for the purposes of this appeal we must assume) 1 that from the time the picketing began, Local 959 pickets parked their cars in the Brown Jug parking lot, obstructed customer access to the parking lot and store, and picketed on Brown Jug’s property. Brown Jug’s counsel wrote to Local 959 in March 1982 advising that picketers were trespassing on Brown Jug property and demanding that they stop. The picketing continued through August 1982.
Brown Jug filed suit against Local 959 and 25 Jane and John Does on March 30, 1982. In its initial complaint, it alleged trespass, blocking and obstructing access to the parking lot, and assault, disorderly conduct and harassment. It also claimed that Local 959’s actions had led to a loss of business. In an аmended complaint, Brown Jug eliminated the count for assault, disorderly conduct and harassment, added a count alleging negligent supervision and direction of picketers, and dropped the allegation that the store had lost business. It sought compensatory 2 and punitive damages and a permanent injunction. 3
Brown Jug admits that it has suffered no loss of sales, business or good will as a result of the picketing. The value of its property has not decrеased. In fact, sales of products distributed by Anchorage Cold Storage increased during the period the Wasilla store was picketed.
Local 959 moved for summary judgment in June 1983 claiming (1) that it could not be responsible for the acts of unidentified agents, (2) that it could not be held liable *935 for trespass since Brown Jug had suffered no damages, and (3) that federal labor law pre-empted state jurisdiction оver the case. The trial court granted summary judgment to Local 959. Its order did not specify the basis for dismissing Brown Jug’s complaint. Brown Jug’s motion for reconsideration was denied, and this appeal followed.
II. PRE-EMPTION OF STATE COURT JURISDICTION
Local 959’s motion for summary judgment was based in part on a contention that the state court’s jurisdiction over this action was pre-empted under the National Labor Relations Act (NLRA) (29 U.S.C. § 151 et seq.). Ordinarily, thе NLRA preempts state court jurisdiction over activities that are protected or prohibited under the Act.
San Diego Building Trades Council v. Garmon,
On appeal, Brown Jug argues that state court jurisdiction over this action is not pre-empted. It agrеes that Local 959 is entitled to engage ⅛ consumer boycott picketing and asserts that it challenges only Local 959’s right to trespass on its property and block access to its parking lot. Brown Jug contends that, under recent decisions of the United States Supreme Court, state courts clearly have jurisdiction over cases involving trespass and obstruction of access.
The leading case on pre-emption by the NLRA is
San Diego Trades Council v. Garmon,
In its 1978 decision in
Sears, Roebuck & Co. v. Carpenters,
For activities which are arguably prohibited under the NLRA, it is necessary to determine first, whether a significant state interest exists in protecting citizens from the challenged conduct, and second, whether the exercise of state jurisdiction entails “little risk of interference with the regulatory jurisdiction of the Labor Board.”

In determining that the arguably protected character of the union’s activities did not prevent the state court from exercising jurisdiction over the trespass action, the Court adopted a different analysis. It noted first that “to the extent the Union’s picketing was arguably protected, there existed a potential overlap between the controversy presented to the state court and that which the Union might have brought before the NLRB.”
Id.
at 200-201,
[T]he primary-jurisdiction rationale does not provide a sufficient justification for pre-empting state jurisdiction over arguably protected conduct when the pаrty who could have presented the protection issue to the Board has not done so and the other party to the dispute has no acceptable means of doing so.
Id.
at 202-3,
The Supreme Court’s holding in
Sears
is determinative in the instant case. Since Brown Jug does not contend that the picketing itself was prohibited, and since the NLRA does not normally concern itself with the location of picketing,
5
Local 959’s activities were not arguably prohibited un-
*937
der the NLRA.
6
We therefore need not apply the “arguably prohibited” prong of
Sears.
The union’s activity was arguably protected, however. The consumer boycott picket itself, as Brown Jug concedes, was protected under the NLRA. The trespasso-ry nature of the picketing might arguably also be protected: the union might have argued that it could not effeсtively have exercised its rights to carry on consumer boycott picketing without trespassing on Brown Jug’s property, and therefore that the trespass was protected.
See Hudgens v. NLRB,
The issue which could have been presented to the NLRB, moreover, is identical to that which could have been submitted in
Sears:
whether trespassory picketing was protected under the NLRA. The
Sears
court concluded that trespassory picketing is so unlikely to be protected that, when a union does not invoke the jurisdiction of the NLRB, the issue may generally be submitted to state courts without significant risk that federal law will be misinterpreted.

Local 959 claims that
Sears
is distinguishable from the instant case because Brown Jug, unlike Sears, never moved for a preliminary injunction. It contends that, had Brown Jug obtained an injunction, the union could have filed unfair labor practice charges before the NLRB. This argument is without merit. Local 959 could have filed unfair labor practice charges when Brown Jug demanded that it stop trespassing or when Brown Jug filed suit in this case.

III. ABSENCE OF COMPENSABLE DAMAGES
Local 959’s second argument is that it cannot be liable for trespass, since Brown *938 Jug has admitted that it suffered no damages. It cites Restatement (Second) of Torts § 165 (1965), which states that:
One who recklessly or negligently, or as a result of an abnormally dangerous activity, enters land in the possession of another or causes a thing or third person so to enter is subject to liability to the possessor if, but оnly if, his presence or the presence of the thing or third person upon the land causes harm to the land, to the possessor, or to a thing or a third person in whose security the possessor has a legally protected interest.
It argues that, since Brown Jug has admitted that the trespass caused no harm to Brown Jug’s land or business interests, the union cannot be subject to liability.
Brown Jug’s first amended comрlaint alleges that Jane and John Does 1 through 25 “committed repeated acts of intentional trespass,” that they did so “pursuant to a plan conceived and adopted by the Teamsters and their agents,” (emphasis added) and that the Teamsters had refused to remove the picketers from Brown Jug’s property when requested to do so. It also alleges that, in accordance with a plan conceived and adopted by the Teamsters, the Does “intentionally blocked, hindered and obstructed access to and egress from the private parking lot and access road at the Wasilla outlet.” The complaint thus clearly alleges acts of intentional trespass.
The Restatement section cited by Local 959 refers to reckless or negligent trespass. Under Restatement of Torts § 163 (1965):
One who intentionally enters land in the possession of another is subject to liability to the possessor for a trespass, although his presence on the land causes no harm to the land, its possessor, or to any thing or person in whose security the possessor has a legally protected interest.
Thus, if Local 959 or its agents intentionally trespassed on Brown Jug’s property, the union may at least be liable for nominal damages. The union has presented no evidence with its summary judgment motion to prove that there was no trespass. An intentional entry onto the land of another constitutes intentional trespass even if the trespasser believes that he or she has the right to be on the land. Restatement (Second) of Torts § 164 (1965). Moreover, once a trespass is established, the burden of proof is on the trespasser to show that it was not willful.
Alaska Placer Co. v. Lee,
IV. LOCAL 959’s LIABILITY FOR THE ACTIONS OF UNIDENTIFIED PICKETERS
Local 959’s final argument in support of summary judgment is that it cannot be held responsible for the actions of picketers whose identities have not been established. The union concedes that it is liable for the actions of its agents who are acting within the scope of their agency. It argues, however, that unless the alleged trespassers are identified, “the officious intermeddler could not be distinguished from the agent acting within the scope of his authority.” It claims that since Brown Jug has admitted that it cannot identify any individual picketers who engaged in trespassory activity the union cannot be held liable for their actions.
Brown Jug has submitted evidence that Local 959 organized and directed the picketing that occurred at the Wasilla store. It has also submitted evidence that the persons who allegedly trespassed were participating in the union’s consumer boycott picketing and carried Local 959 signs. It argues that a trier of fact could conclude from this evidence that the picketers were agents of the union. We аgree.
While it is possible that persons who trespassed on Brown Jug’s property
*939
were not representatives of the union, their agency is a question of fact which we must resolve, for purposes of summary judgment, in favor of Brown Jug.
Bowers v. Alaska State Employees Federal Credit Union,
REVERSED and REMANDED.
Notes
.The parties disagree on whether Local 959 picketers trespassed on Brown Jug's property and obstructed access to its parking lot. In reviewing the grant of a summary judgment motion, we must view all factual questions in the light most favorable to the party opposing the motion.
Bowers v. Alaska State Employees Federal Credit Union,
. Brown Jug has subsequently abandoned its claim for compensatory damages.
. In its amended complaint, Brown Jug sought a preliminary as well аs a permanent injunction. Brown Jug never moved below for a preliminary injunction, however.
. A union’s trespass is not, in itself, an unfair labor practice under the NLRA. See generally § 8(b) of the Act, 29 U.S.C. § 158(b). Thus, the mere fact of a union trespass does not enable a property owner to invoke the Board’s jurisdiction.

See Sears,
. Obstruction of consumer access to the Brown Jug store could be viewed as arguably prohibited under the NLRA insofar as it turned the union's activity into a secondary boycott. Local 959 does not argue that the court’s jurisdiction was pre-empted on this basis, and we do not address the issue.
. The Court concluded that the trespassory picketing at issue in
Sears
was arguably protected for similar reasons.
Sears
We note that we are not asked to rule on the merits of this argument, but merely on whether its existence is sufficient to pre-empt state court jurisdiction. We exprеss no opinion on the question of whether the allegedly trespassory nature of the picketing was itself protected under the NLRA.

See Shirley v. Retail Store Employee’s Union,
. See note 4, supra.
. Also without merit is Local 959’s contention that, since Brown Jug has suffered no compen-sable damage, the state has no strong interest in asserting jurisdiction over this case. In Sears, the Court made it clear that, at least in cases where arguably prohibited conduct is not at issue, state jurisdiction over trespass actions would not be pre-empted unless unfair labor practice charges were filed with the NLRB.
. Local 959 does not raise the issue of whether Brown Jug may be awarded punitive damages absent a showing that it suffered compensable damages, and we therefore do not address the issue.
