Off-the-clock
So I've been working a whataburger for a few months now, but today, for some reason, I wasn't having the best day. I was late due to a vehicle issue, at night so I had to wake someone up to allow me to drive another car(old truck wasn't working again 😞), and then I was working and for some reason i would just get so annoyed at how messy my station was so I'd be like working then I see that it's even a little messy and I clean it up but like I'd get upset. And then at the end of my shift me and my manager find out I didnt actually clock in for 5 hours and in my head I wasn't thinking about that, I also assumed I was there and I was clocked in the whole time during work but I wasn't...soo what I'm trying to say is, is it illegal to not clock in, just curious if I can work one day voluntarily for free?
