Enjoyable coworkers, but overwhelming training and low pay - Avis employé Front End Associate Target

i ended up being trained all over the store. from pushing truck,SFS,OPU,cafe,grocery,front end,stocking etc. i even had management ask ME an employee on who was going to come in and cover. when they made the schedules. i was making 15$ an hr at the time. i went and got a part-time job,they found out and got upset. I ended up leaving because I needed to find a job that would let me work up to eight hours of both jobs instead of spending 10 to 12 hour shifts up to a week on with Target
