What the last guy said and...
guarantee is 75 hours.....if you call them up and re-arrange your days off, you can pick up enough trips to make about 100 hrs credit a month, if they're not calling you too much...I did that and worked about 10 days a month when I was on reserve.......as far as the early release, I found that they respond better when you call them up on the phone...the computer one didn't work for me..maybe someone else had better luck with that. If you need to be let off early, just give them a call, sometimes they will, sometimes they won't....
