Dollar Tree review: terrible manager

I work at this store currently and the manager here Dora Taylor constantly changes the work schedule with notifying any of the employees. She puts up a new shedule every three days. So i have to constantly call to check it. Its hard to call up there because the phone line is messed up and she wont get it fixed. I showed up for work ready to do my shift and she changed the schedule right after i clocked in. Then she had scheduled me to come in on a day i was off and had already seen the new schedule. Because i wasnt aware of the change because she failed to notify me, she threatened to fire me because i didnt show up. She always bothers me while im woring. Saying my too slow at scaning items saying if i dont know what im doing i would be terminated. I always work over my time because she takes forever on her lunch breaks. On weekends we run out change sometimes so we have to put up signs saying change needed. The store was always dirty and she did nothing but say rude things and eat every chance she got. Im sharing this because she needs to fired.
