Hold on here guys. Where did the "not call in" bit suddenly come from? Even in Holland this will have consequences. If I don't show up and don't call I'll probably receive a written statement that I'll lose my job the next time I do that. You need two of these statements at the least to have me fired. If a company wants to fire you and you have a indefinate contract, they need to do that via a judge. You can't just fire somebody for no good reason. But if you have two of these statements in your personal file, things do get a lot easier.
Therefor I would always call in a say that I won't work because I am going to use my right to protest. Employers could still give me such a written statement but it would carry much much less weight then one for being unannounced awol.
