You admit that you don't care about the work you do. Why try to spin it?
I do care about the work I do. However, I care much more about ensuring that I get properly compensated for the work that I do. There are no freebees in life. If you want 110% out of me, you're going to have to compensate me for that extra 10%; and trust me it's going to cost you more than 10% beyond what my 100% compensation is.
My department currently has 8 employees. We're all offered 8 hours of Overtime a week. I don't work it. Why not?, you ask. Very simple.... 8 hours x 8 employees = 64 man hours = we need 2 more full time employees in the department.
