Cash Saver

I have been working at this store for 3 months. And ever since I have been treated different. I am the only Mexican up ther and like everyone else I call in when I have a. Emergency. Now thwr making it an issue I have 4 small kids and a grandpa I take care of who has dementia and I work as a cashier to make ends meet. Randy treats people with disrespect. He cusses at us employers and yells at us when he thinks we not doing good enough job. I like my job but the manager has issues. I really do believe he is racist he fire my gay friend and now me. Everyone is white but us smh.. I need something to be done about this PLEASE. H e is taking advantage.
