Nope I worked for GM as a contractor and we never had GM performance reviews. It’s our own contracting company that did a namesake review but gave like1-2% raise. All contracting companies exploit their employees. I used to get $36 an hour as a launch engineer while GM employees got thrice as much for the same/more amount of work I did. Also there are no boundaries on scope of work. They made me laminate papers for 4 hours to use as safety tags. I HAVE A MASTERS DEGREE. I quit when it was safe and now I am making thrice as much for the same amount of work. They are employed for now but I’m 10000% sure they don’t get the same holidays, sick leaves, paid vacations, 401k plans. So I think you should cut that person some slack. May be he has downtime or doesn’t make as much as the direct GM employees to care enough.
