No point to waste time fighting such a management. Vote with your feet. There are many good jobs out ther.
More are in the pipeline. Trouble is it makes it only harder for those who stay behind though. Not fun for them right now. Latest I heard is the in-flight relief guys getting €7000+, i.e. above the original parc contract you mentioned in one of your posts. (BTW, where did you see it? Parc did not have it on its site) Its more dough than the an expat skipper makes, let alone the poor local drivers.
