Questions about dates for work

1. Whats the earliest people start?

2. Whats the latest people work?

3. I got in to one grad program but i applied to another that i would prefer. I will use the dates around my safety program. I wont know til may if i get in to the better program. The better program would allow me to work an extra 3 weeks or so. Can i add time to the end of my contract? If i stay will i still get bonus for the extra time?

1. Seasonal jobs start as early as mid March I believe. It's all cleaning and that sort of thing.

2. Mid to late November is the latest seasonals stay, doing cleanup crew and such.

3. They are always more than happy to keep you past the end of your contract if you're willing. They get desperate late in the summer. And yes, you still keep accumulating your bonus for the extended time.
