i gained experience, exposure to the real society, personal, professional and financial development. I feel, discrimination & bullying, as well.
Work in a shift is almost physical, a bit of mental. I learned & accept that co-workers, supervisors also, sometimes do not consider an individual as human. The pressure that a supervisor imposes an employee to be done with all the works, without considering the load, on busy days, on time is so stressful. It is a very good feeling if a supervisor show appreciation on the efficient performance of duty and give a person the chance to learn a different task, aside from what he/she is doing every shift.
