I went out after listening from the HR "It's normal that a boss yelled to people. Maybe you are to emotional. Next time he'll make you and formal complain if you do something wrong. We can settle this way or you want to look for another company?".
I'm not kidding....
I arrived to work full-time from Brazil and just after my arrive they said that I couldn't start immediately because they don't needed (Holliday season) and after a month waiting, in a new country without a job they made me start PART TIME! Just after a year i started Full time.
They don't care about people. It's just sad how a company can be this bad to people.
