People sometimes assume that bullying ends in high school. Unfortunately, that's not true. It often extends into the workplace. It's not something that stops as people grow older.
While workers in some positions do have contracts outlining how long they will hold a job and why the position can be terminated, among other things, this is often just true for high-level executives and other specialized workers.

Workplace discrimination takes many forms. Maybe you didn't get hired because of your gender, unable to break into a workplace dominated by the opposite sex. Maybe you got to an interview, but you knew your race meant you never really had a shot. Perhaps you got passed over for promotions that you deserved. Maybe you faced harassment from co-workers and supervisors over things like age or sexual orientation.
