Cons ? A lot... From one day to the next, because the boss is in a bad mood, he will tell you that your work is bad and that you do not do enough. Whereas a few weeks earlier everything was going great. I have never seen so many colleagues cry because the boss exerts so much pressure every minute of every day. Even if you do your best and try your best to make things better, you will end up being mistreated and gently kicked out. Flees!
