The truth is no union really wants to go on strike for a variety of reasons. Without the right to strike contract negotiations are simply a pantomime of a cap in hand. Holding a strike for longer than two weeks on the one hand is next to impossible and on the other risky for the union more than the employer. Any strike of any kind that I have researched has consistently proved workers, especially in health, education or government professional occupations feel deep seeded guilt at abandoning their students/patients/clients . However, in every case, the underlining cause of the strike  is management incompetence. No exceptions.  Whenever I see a strike, knowing of the many factors that can lead to a complete collapse of the union or the strike, and see a workforce standing together long enough to march on the picket line I know there is something up with management which is causing the worker dissatisfaction. I successful strike may improve beneficial to all.
