During peaks seasons, if the CM has year or more of seniority then they can expect to work full 8 hour shifts, five days a week. But you can always request more hours it is less than 40—it isn’t too hard to fill up a schedule. In the off-season however, it depends a lot on the CM’s availability. CRs are only required to work Sat/Sun/ Friday evenings/holidays so they are looking at 18 hours unless you request more.
Just get use to these words: Extended/ Can you stay/ Would you be willing/ Happens all the time. Worked for 3 months and only got off 3x at my normal time. One time I got extended to 4am. Could have stayed longer but the tooth picks in my eyes were against union labor laws.
