I've been working at Target for 3 weeks now, and they were aware when I interviewed and was hired that I couldn't work past 4:30pm on Saturdays, but I just took a look at my schedule and realized they have me scheduled tomorrow (Saturday) from 5pm-closing. Do I talk to HR about this? Would they just switch my hours or something? I don't want to make them mad or anything, but I just can't work those hours.
