Illegal Acts in Strike: Individual, NOT Collective; EXCEPT: Pervasive, widespead

A strike otherwise valid, if violent in character, may be placed beyond the pale. Care is to be taken, however, especially where an unfair labor practice is involved, to avoid stamping it with illegality just because it is tainted by such acts. To avoid rendering illusory the recognition of the right to strike, responsibility in such a case should be individual and not collective. A different conclusion would be called for, of course, if the existence of force while the strike lasts is pervasive and widespread, consistently and deliberately resorted to as a matter of policy. It could be reasonably concluded then that even if justified as to ends, it becomes illegal because of the means employed. (G.R. No. L-32853; September 25, 1981)
