I reported a safety issue against one person and they don't like it. That was probably the reason for let me go

My biggest mistake was trying to help coworkers. As a welder I did good

That's simple OT was the only thing

I was working as a robotic welder for 5 months in that company until one day I had a minor injury at work, so I went to the clinic and the doctor find I muscle problem in my elbow. After a week the doctor released me from care and the company don't let me come back to work and fired me up for no reason or explanation. I recommend don't trust VSSI staffing services
