There was an incident at my work with the way I handled a call (which I disagree with) that has resulted in a warning. They made me sign a form that included words agreeing that my tone was "rude" and "condescending" but I felt I had no choice in the spot. Now they are forcing me to work away from home. I was originally hired for an office near my house but then there was no space so they gave me a remote working option. I don't know if there is anything legally that I can do to keep my work from home arrangement but I'm also worried about them firing me due to an email they forced me to send as a sort of confirmation to that bad incident with a client
