Respective counsel for Petitioner (Union) and the Respondent (Board) stipulated that the sole issue may he stated thus:

“Whether, under the circumstances 0f this case, the Board properly concluded that petitioner by picketing Gate 3A of the General Electric ‘Appliance Park’ plant at a time when General Eiectric was engaged in a labor digpute with the petitioner violated secüon g(b) (4) (A) of tbe National Labor Reiations Act, as amended ”1

The Union has asked us to review and set aside, and the Board asks enforcement of, its order that the Union cease and desist from inducing or encouraging the employees of certain named contractors “or any other employer, except GeneraI Electric Company” to engage in a strike or a concerted refusal in the course of their employment to perform certain work or services where an object is to force or require such employers “or any other employer or person, to cease doing business with General Electric CompanF-

Intervenor, General Electric (Company) maintains a manufacturing plant at Appliance Park, Louisville, Kentucky, where it produces automatic washers, driers, dish washers and other household appliances. The Company during 1957 shipped in interstate commerce finished products valued in excess of $10 million. Some 13 plant buildings are located on a 1.000 acre tract, substantially square, with about 6,600 feet to the side. Surrounding the area is a ditch of such width and depth that vehicles can enter and leave the premises only on five roadwa^s across culverts. At the entrance and on either side of each roadway are metal stanchions, between which a chain may be fastened to block the movement 0f vehicles during night hours and on non-working days. These entranceways numbered 2, 3, 3A, 4 and 5, are herein called “gates.” To various classes of *284vehicles the Company’s plant protection department, years before the events here critical, had issued stickers of varying size, shape and color. Each vehicle, whether that of a Company employee, or an employee of a contractor, a supplier or the like could readily be identified by tile plant guards simply by examination of the type of sticker carried on the windshield. Employees of the Company had been authorized to use Gates 2, 3, 4 and 5, but not Gate 3A.

„ , , The Union m July, 1958 called a lawful strike against the Company. At that time the Company had some 10,500 employees at Appliance Park, of whom substantially more than one-half (possibly 7,600) were production and maintenance employees for whom the Union had been certified as bargaining representative Picketing immediately commenced at all gates, including Gate 3A. The picketing was peaceful, the pickets carrying signs reading:

(< Local 761 On Strike G. E. Unfair”

The Company kept the plants open, and it was found that more than 2,000 employees represented by the Union continued to work during the strike as did many others not within the bargaining Un^'

The Company at that time had outstanding various contracts with some 12 employers. Their jobs included installation, repair and alteration of equipment, converting machinery for products changeovers, retooling, rearrangement of conveyors, installation of presses and the like. Some employers were constructing a truck dock, erecting an air shelter, and laying in a mezzanine floor in one of the plant buildings. General maintenance work beyond the skills or the available manpower of the Company personnel engaged for that purpose was also let to outside contractors. Some of the work in the various collateral lines had been the subject of such contracts over a period of years.

In earlier experience, some 22 jurisdictional disputes among the craft union employees of the various contractors had resulted in picket lines at gates normally used by the Company employees, thus keeping out the General Electric employees as well as those of the contractors. By 1954, the Company had issued: written instructions to its plant security-people that use of Gate 3A was to be limited to the independent contractors, and their employees, in order to eliminate interference with access by Company employees. Likewise, all contractorg and thdr empIoyees had been in_ gtructed to enter and to Jeave the Com_. pany premises only through Gate 3A. Thus> the Company had established Gate-3A for tbe gole and separate use of the. contractors and their employees at a. point some 550 feet from the next nearest ga£e

For some years signs at Gate 3A had' carried posted notices of the limitation on permitted use, and at least since January, 1958, a large sign erected there had read:

“Gate 3-A jpor Employees Of Contractors —Only— G. E. Employees Use Other Gates”

The trial examiner’s discussion of the case, he said, was “based upon the premise that Gate 3-A was reserved exclusively for contractors, their employees and suppliers, and that the Respondent [Union], in picketing at that Gate, did not seek to solicit any of the Company’s employees to cease work.” Also he con-eluded that while the Union’s appeal at Gate 3A was to secondary employees only, i. e., to employees of persons other than General Electric, the Union picketing there was part of “traditional primary strike action,” and hence was for the same lawful object as the picketing at the other four gates. He recommended that the unfair labor practice complaint be dismissed, having concluded that section 8(b) (4) (A) does not protect the *285business of a neutral employer within the situs of a primary dispute. The Board substantially adopted the findings of the trial examiner, but disapproved his opinion that the picketing at Gate 3A was “traditional” and was protected by the Act.

„ „ ,, , The Board found from the record as a whole that only the neutral contractors employees were permitted to use Gate 3A as the Union was well aware _ The Board concluded that the Union s object in picketmg at Gate 3A was to enmesh these employees of the neutral employers in its dispute with the Company Such purpose is shown not only by the picketing at gate 3-A but also by the oral appeals to the employees of neutrals not to cross the picket line.” The Board therefore based its order on its conclusion that: “the Respondent violated Section 8(b) (4) ( ) o e c y in ucmg an en couragmg the employees of independent contractors to engage m a concerted refusal to work with an object of forcing the independent contractors to cease do-mg business with the Company.

We think the Board has correctly evaluated the findings of the trial examiner as well as its own. In any of these secondary boycott situations the ultimate determination turns upon the union’s objective. Often “The line is fine,”2 and circumstances of the particular case must supply the answer to which way the chips are to fall. _ Here the question may be stated: was it an object of the strike to induce or encourage the em-p 0^es °. e sevel'a eon rac ors no of the primary employer-to engage m concerted refusal m the course of their , , ^ „ .. . . employment to perform their own work * J . or to render services so that their em- , .... ... ployers would cease doing business with General Electric?

In the Seafarers case now relied upon by the Union, we considered such questions and found the union’s exercise of its section 13 3 rights was not in violation of section 8(b) (4) (A). There, however, the pickets (1) identified themselves specifically as striking only their primary employer, (2) proclaimed by signs clearly showing that they had no dispute with the secondary employer, (3) distributed leaflets which explained in detaü nQt Qnly their own purpose and ^ reagon picketing was conducted at ^ particu]ar locatim¡ but especially ex-duded the secondary employer and its j Moreover the primary employer had ^ itg ghip in the second_ ary employer>g yards and only tbere. after were its employees withdrawn; the ghip had nQ other berth at which the union>g organizational efforts might be bIicized and the veggeI normaIly was at gea monthg Qn end with itg crew ghiftg rotated and tran rted back and forth by helicopter- The operations as conducted by the primary employer not on¡y had luded the possibiIity of picketing the ghi directl but as evi. dence Qf ^ j >s purpoBe the pri. ma em j during tbe night laeed a crew aboard ^ veggel and towed it away. Such circumstances and such conduct, we concluded, made it clear that the union intended — not to shut down the neutral’s operations, but to conduct lawful strike activities against the primary employer for the achievement of a protected objective.

The gituation here ig vastly different. When the gtrike wag called in Ju]y> 1958; the Union pieketed alJ gates> including ^ í<Mogt) .f not ^ of the independent contractors’ employees refused to cross ^ and did not work during ^ » , -o- i l the strike, the Board found. Pickets , ~ , 0 A . ,, , 4.1 at Gate 3A m some cases refused neutral . . . , employees permission to get their tools, otherg were told to ^ paggeg at the Union office_ otberg were told; in effect> to “Go on home.” There was no showing that Company employees made any attempt to utilize Gate 3A. We need not *286detail additional items.4 It is sufficient to note that the Board’s findings do not lack support in substantial evidence on the record considered as a whole, and we are bound by those findings.5

This was no case of a union’s seeking “to influence two employees of a customer of the mill not to cross the picket line.”6 Rather, the Board reasonably could find, as it did find, that the Union by peaceful picketing to be sure, but effectively nonetheless, sought to encourage the employees of the independent contractors to engage in a concerted refusal to perform any services for their employers in the course of their employment and thus to force their employers to cease doing business with the ComPany’7

The objective of the picketing at Gate 3A as so found by the Board brings this case within the statute’s range.8 The “fine” line must be drawn in favor of Board’s order,

The order of the Board will be enforced.
