The same effect of stopping deliveries from Sigma to Megalomania may be achieved, but the picketing is presumably illegal because it is directed at a secondary employer. In cases involving secondary pressure directed at a customer of the primary employer, it is necessary to distinguish between efforts to induce a secondary strike and efforts to induce consumer boycotts. The issue here is substantially the same as secondary pressure directed at a supplier . Direct efforts by one employer to assist another in resisting the effects of a strike may cause the former to lose its secondary status. Megalomania also manufactures whickles, which it sells to Alpha Assembly.
Alpha makes wompots, a critical component of which is the whickle.
Alpha also supplies Gamma with retail wompots. The Extrusion Workers represent production and maintenance workers at Megalomania. Businesses are permitted to maintain their normal relationships during a labor dispute without losing their neutrality. Therefore, the normal rules limiting secondary pressure would limit the ability of the Extrusion Workers to apply pressure on Alpha or Gamma during a dispute with Megalomania. Assume, however, that Megalomania cannot fill its orders with Gamma for whippets.
