They are opposed to a lack of job opportunties after graduating
Those lack of opportunities are largely down to their own incompetence. I'm recruiting at the very minute for someone, preferably not long graduated - and while the subject studied isn't important, what's important is work experience in a relevant setting. I don't care if they've studied history, geography, biology, whatever - but I expect them to have gained some experience in an office environment during their studies. Fooling around the mountains during the holidays is *not* how to get hired.
That's the real problem in Poland - "I HAVE PAPERS AND I EXPECT A GOOD JOB AS A MANAGER", because - that's how it worked during Communism.
and 'smieciowe umowy' (trashy job contracts which exclude benefits, paid holdays or old-age pensions).
Trashy people tend to get trashy contracts. Good people get good contracts - it's the way of the land.
Will this movement take off in Poland?
No. The sensible, educated classes will never back it - and they will forever be seen as the ones who simply expect life to hand everything to them on a plate.
