I'm not familiar with regulations on strikes, if any. That aside, you don't need to be exploited to have a moral reason to go on strike. A strike is roughly equivalent to a mass layoff, but from the employee side. We hear often how employers can let people go "for no reason, at any time", so the same should apply to employees. Employees can "let go" of the employer for no reason, at any time, and agree or not to "rehire" the employer "at will". Please note that I'm not supporting or criticizing this particular strike. I'm just saying that if we understand unions (at least voluntary ones) as a way to increase employees' bargaining power, they should be able to engage in cutthroat, "Greed is good" negotiation under free markets; all they need is to feel that they can get more, irrespective of what they have.
