Not too hard, ?. It seems the store I work in they are fairly accommodating when requesting time off as long as you put it in when its something like two week) . %10 ( I know its not much..but at least it something)
If you want more hours, ask them and let them know.
Cons
If you change your availability to smaller window, they may give you less hours.
Work environment is like no other! Friendly associates, management is understanding and willing to work with you through any issues, and location is great! Room for growth is definitely present.
Cons
No cons currently. Doesn't seem like any major cons would arise either.
