Help with WorkCover and Workplace not being fairq

Good Morning,

I injured my lumbar earlier in feb, bulged disc, pain is pretty bad and I'm at physio 3 times a week and trying to work 4 hours twice a week, but its taking so long and my ability to walk normally is impacted.

But here is the problem, on one of my first day back on my 4 hour days, another employee put me under a strain of coercion , saying I should be forcing my doctor sign me off, that made me feel uncomfortable, I left and eventually had to go ask the doctor for some Diazepam to help me deal with the situation.

I know they had a workplace bully meeting while I wasn't there and I just feel nothing good came out of that, probably even worse...

but the real kicker now, I just opened my payslip

it used to say COMPANY pty ltd etc

now says COMPANY LABOR HIRE pty ltd

I think they've changed my position without letting me know, to set me up to boot me.

My mental health is so down, my anxiety is through the roof, I've had to take 5 diazepams this morning just to calm down and I'm really at breaking point.

I never bully anyone, I'd never do this to anyone, so it's frustrating that it gets done to me.

Is there anyone that can offer any advice please, i'm at my limt.

Thank you so much in advance
