Are you truly this clueless?
I will try to use little words just for you:
They give me 9 hours of work.
I get it done in 7.5.
I get paid for 8.
.5 * 4 = 2
(We start at 9 on Monday and I generally get what little OT that I get on that day.)
Comprende?
You're conflating planned days/dispatches to paid hours in all previous posts. I've been talking about hours worked this whole time. I responded to your punch in, lunch, punch out times and that conflicts with everything else you've said.
When it comes down to it, you get 8 straight hours everyday, except Monday apparently, but work 7.5.
When you said you average 9 hours a day, you failed to mention that you are dispatched 9 hrs of work.
This also points out that your center's time studies are way to generous. They are all fantasy land in my center.
