Unless there is an emergency, O/T is not mandatory, as employees we can stay or go . Mgmt can ask and we can say no, it is not a job action. You're probably not an airline employee either. The company can't get an injunction for employees not working O/T.
Not doing your job, calling in sick, walkouts, these are things that can be done and the company has the right to seek and expect protection from unions. As long as both the company and the employees abide by the rules and guidelines set forth in the company regulations each party is acting legally.
No one should feel pressured not to work, but it's kind of a unwritten rule within the union. I understand that the NOW generation only care about themselves. That each persons situation can be looked at differently. If your financial situation is so bad that you require O/T just to survive you, should look for a better paying job or check your credit card activity. This would exclude medical reasons I get that before you throw that in.
By you saying employees should adapt that only shows me your are from the I Got Mine generation and that you care less about your coworkers.
