Depends on the center you will be working at. Small sorts, will generally be 3.5 hrs a day, which is the minimum guaranteed by the contract. Larger sorts, you could get 4-4.5 hrs a day and perhaps a little more during peak season (Thanksgiving-Christmas). Start times, 4:30ish am and out around 8:30-8:45am to be conservative here. Peak could see start times as early as 3am.
