Dollar Tree review: unethical behavior

This passed Saturday (December 5th) I was working the mid shift at Dollar tree. I am a cashier, and my shift was from 12:30 to 5:30. My boss(Store Manager Norma Collins) made a false accusation toward my work performance, and I disagreed with her. Now keep in mind she has gotten almost more than 10 plus compliments about my costumer service skills from many different costumers since I have been working there, but the reason why she kept complaining is because of her own personal prejudiced against me. She spoke to me very rude and disrespectful when I disagreed with her about my work performance, and I told her I felt she was being exactly how she was acting. I told her she was rude, disrespectful, and that her attitude was nasty, and I did not appreciate the way she was speaking to me. After we had words. She told me to clock out, and tried to fire me, but you cannot fire someone because they disagree with you, and secondly as I was walking out of the store to leave for the day, after she asked me to. She closed the door behind me, but before she shut it, she openly and boldly called me a ###! I am a proud homosexual male, and I should not have to go to work, and or deal with a person having a personal issue with me because of who I am. I would like for action to be taken against her, and I would like to be transferred to a different location. What she called me and how she treated me is discrimination to the maximum level, and it is unacceptable. This all took place at the Dollar Tree location is Hazel Park Michigan on 9 mile and John R, next to Krogers. I am associate Caleb Merritt. Thank you!
