But, I actually have. I come in when I'm scheduled at 1:00 -1:30, work my 8 or 9 hours. Do the same on my 6th day punch.
I'm classified as a part timer, get PT pay and PT pension, but haven't worked less than 2000 hours a year since my first year.
Bottom line is, PT can be viable. But, I am treated like full time and think I should be compensated accordingly.
