I use to work for Catholic Charities from Aug 16th till Oct 20th of 2017 the first couple weeks where fine until one of there Supervisors Raual started to degrade me in front of staff and clients and making me feel like I was stupid and less of a person, I informed my bosses of the situation they did little to nothing about it so I went to HR where they said they investigated the situation nothing ever happened they said they couldn't find any proof of what I said, then my last month of my employment I was told by my supervisor I wasn't allowed to wear a face mask to stop people from spitting in my mouth when they are blowing into the machine to test for alcohol and because of this I got sick with bronchitis I informed my work they did nothing I got sick again 3 weeks later with severe Bronchitis and was in the hospital for 2 days because I could barely breath and I received a letter saying I was terminated for not showing up to work and not calling in because I couldn't breath to even talk and now in sitting in the welfare office and was talking to the security guards I use to work with and the vice president came up to me and was very rude saying I was disrupting there work and that I'm not allowed to talk to his employees and that I'm fine to be a client but I need to act like a client I didn't know I wasn't a human being and wasn't allowed to talk to someone everyone here is rude and treats people like they are bellow them but then representing themselves as people who are here to help this is a terrible place to work and to be a client of.
