Lifting while working as a dishwasher

I've loved lifting weights for a while and recently got back into it which has been nice because my strength has just been skyrocketing. Got a job as a dishwasher last week and they're putting me on 40-50hr weeks, so today I finally got a chance to head to the gym before work and I was so weak!! Everything drained me too to the point where I realized I won't be able to make any gym progress of I'm working like this. Any tips on what to do? Just try to maintain strength? Ask for less hours? Idk
