I've recently been disciplined and placed on an indefinite final written warning by my employer because of disruptive behaviour including being short with colleagues and having "negative body language".
Around the time my mood deteriorated, I was diagnosed with depression by my GP, she wanted to sign me off but I couldn't afford to live on SSP. I've since been on medication and have a psychiatrist and community coordinator. In my grievance meeting my employer stated that because I've never handed in a sick note, they think I'm lying about the depression and therefore will make no allowances for it affecting my mood and ability to cope with stress.
What should I do? I'm finding it so hard to think straight and feel so bullied by them.
