Well, this has definitely been eye opening. I have read some stuff on here about PT, but most of the comments are somewhat old so I don't know if things have improved?
As for both bonus structures...
PT 0-500 hours = no bonus
501-1040 hours = half bonus ($5 for calls 2-5 and $10 for any call past 5)
After probation = $10 for calls 2-5 and $20 beyond 5 calls.
There's an extra $10/call if you work the graveyard shift
Norcal is a straight bonus of $3/call.
