@Delph: "less protection" to employees! Why not slavery? It would be best for those employers;). I bet neither that employer nor anyone in his family have ever worked under garbage contracts. I "love" the "it's good for you but it isn't good for me" attitude.
Well, what I mean is that some of the more insane provisions (such as the trade union "inspector" being untouchable in work) should be abolished. Of course, the more normal protections should be kept - but for instance, employers should be allowed to inspect whether or not someone is genuinely sick. If Agnieszka is seen in the shopping centre trying on new dresses when she's on sick leave (when pregnant) - then the employer (rather than ZUS) should be allowed to instantly dismiss her for gross misconduct.
I don't think anyone minds that a woman should be able to return to work to the same job and the same conditions, but I do understand why employers get incredibly angry when someone sees two lines on the test and immediately runs off for sick leave.
Au contraire InPolska - I would say a great many bosses in Poland work with zero or very small protection. I could be fired tomorrow with no reason and no compensation, escorted out by a security guard, leave my car keys and phone on the desk and told to fend for myself. I accept that as the flip side of good pay and interesting work and I plan my finances accordingly. I know many people with the same arrangements.
Out of curiosity, was it your choice to work in such a way?
At the bottom end of the scale consider this - you are about to launch a new project and need 3-4 people. Its got a 60% chance of working. If it does not then if you have people on less formal contracts then you could send them off with a thank you note and a good reference and they would have some valuable experience, be able to improve their language etc. That seems mutually beneficial and not exploitation.
Yes, a friend works in this way. He makes it clear from the beginning that the project is new and won't necessarily succeed, but he agrees set goals with the entire team at the beginning. If they meet the goals (and the project succeeds) - then they are given full contracts without time limits as the project is now self financing. It seems to work well.
