I'm new to this job .some of my coworkers are trying to make me quit.Thy directly or indirectly blame me everything wrong,they talk behind my back, they make fun of what i'm doing or what i'm saying , they humiliate me in front of costumers.I'm only working two months and I feel like i'm in a Little hell.The manager is silent and not willing to interfere.I'm not perfect ,I sometimes do mistakes but they are not too many as a new guy.I'm black and I have a foreign accent but not very strong accent .I end up everyday strained and headache.Now i feel like i'm defeated and quiting is not good Choice for me .your suggestion wil be helpful.Thanks
