Management. They’re a clique. If they don’t like you no matter how hard you work or how great you work, they will dig their grubby little hands into your studies to make your life a living hell. Oh you want to excel in your position? Good luck here, once you’re in your position with your base pay, they will exploit you to their fullest ability. They will hire outside at a lower pay just to save money instead of use the people who have experience. No matter your education level, hard work, or time put into the company, they could care less. Even if you think they like you, they don’t. They cannot be changed. Management is the issue.
