being treated unfairly

Zamathenjwa store manager and nkosinami floor manager treat us unfairly they make us sign for thing that are unnecessary 1 of our packers signed because she bought groceries and gave them to her brother because he was at the store and the othe worker was threatened as she was coming back from maternity leave she was told that she was first on the list. Of people she was going to fire she was treted bad she even resigned zama always smoke on our shopfloor every afternoon when we are about too close the store one day she made free meal for us because we won one million that day she was spitting on the floor calling us names especially frontline now she's threatining to fire the staff because they went to 1 of the workers funeral which they were allowed to go too Nami always call the staff vte's which are good for nothing Zama also insult us infront of customers and workers are being fired for minor things but ee are afraid to report him but i just thought enough is enough now
