From our end it is difficult to ascertain your real situation. So many folks will comment or answer negatively because of what they might have experienced personally. I for one, many, many moons ago was in a similar situation. Poor management, poor training, and a group of very disgruntled fellow employees. I guess I had thick skin and a very hard head. I put up with the, what is called now, verbal abuse and snide remarks. Each day I wondered why I stayed on. Then I remembered I needed the money. Eventually all the negativity towards me disappeared. I stayed on for 6 months till I was drafted.
If you have the means to survive without the job quit if not stick to it and ignore the rest. Rise above your circumstances.
