Whether an employer's grant of substantial super-seniority to strike replacements and strikers who return to work is an unfair labor practice under §§ 8(a)(1) and 8(a)(3), even without proof of a subjective antiunion motive.
Holding
Yes. The NLRB could find Erie's 20-year super-seniority plan unlawful based on the plan's inherently discriminatory and destructive effects on protected strike activity, without making a finding of subjective unlawful intent.
Reasoning
The Court explained that subjective intent is relevant in unfair-labor-practice cases but is not indispensable. Intent may be inferred from conduct whose natural, foreseeable consequences are to interfere with protected employee rights or to discriminate in a way that encourages or discourages union activity. An employer ordinarily is held to intend consequences that flow inexorably from its chosen conduct.
Erie's plan discriminated on its face between employees who continued the strike and those who worked during it. Unlike ordinary replacement, which affects only strikers actually replaced, super-seniority affected every striker's future job security. Even strikers who returned to their former jobs would rank below replacements and coworkers who abandoned the strike when future layoffs occurred.
The plan also combined a threat with an inducement. It offered striking employees an extraordinary individual benefit if they returned to work, while diluting the accumulated seniority of employees who remained loyal to the strike. The Board reasonably concluded that this arrangement would undermine mutual support among strikers and seriously weaken the strike itself; the rapid collapse of this strike after the announcement confirmed that practical effect.
Its effects persisted after the strike ended. Rather than ending with the employer's temporary use of replacements, the plan created a lasting division between workers who stayed on strike and workers who crossed it or were hired as replacements. That continuing division impaired the union's ability to bargain and repeatedly reminded employees of the economic penalty attached to striking.
