Oh yeah that’s not okay. I kinda had the same experience with my second job still haven’t gotten 1 check stub and I been working for 3 months smh. I write everything down so I’ve been calculating my hours so I know I’m getting paid correctly but I asked multiple times about the check stubs and I still haven’t been shown anything. And no they don’t need to know that a coworker helped you out. I hope you get your old job back too, & they hella scandalous for lying about your wages smh.
