The company piles up too much workload and expects a high level of accountability while in return the company doesn't provide any benefits for it. Starting salary is usually around a few euros/hour, but they lure employees with some fairytales of possibilities to advance quickly and earn much much more within months, although that never happens.
If you do job well, the management will burden you with more responsibilities, however, this doesn't come with the pay raise but they say, if you do your job well, you'll get one. And then they won't mention the pay raise anymore and they will leave you with all these extra responsibilities and even pile more at some point.
They do appreciate your hard work and contribution, but with a pat on the back and "good job, pal", but once a year when they give pay raises, you'll get a slap in a face with a 5% per year. That's not a raise, that's a humiliation. And when I say "they" and "management", that is of course the CEO because he makes all the decisions.
On top of it all, CEO constantly finds reasons to argue and offend employees and acts as a small tyrant most of the time. He also tirelessly checks the online reviews, so whenever someone says the real truth about the working conditions, he has one of his close associates who clearly lack backbone to submit disingenuous reviews that don't t reflect at all the actual work environment.
