I just can not understand how people like the OP can work at a job that has your rights written down in black and white and they still have no idea what their contractual rights are.
Most jobs hand you a company handbook that has the company rules.
Our job has a contract mutually agreed to by both parties that explain your rights.
Heck, about 1/4 of the master only talks about drugs and alcohol and people still have no idea what the contact says until they read it after the fact.
I carry one with me at all times while on the job, and have one in the can at home.
If you do not take the time to read it over and over in order to keep an 80k plus job a year with benefits, then you are not cut out for much.
The real sad part is that 90% of our workforce who are fired will never make 50% of our package at UPS, not to mention a pension.
