Is taking three days off unreasonable?

I’m a plumbers helper in Brooklyn, live in queens. Last week my transmission was giving me problems, asked for some time off, was declined and drove w my fucked up transmission. Saturday comes and I’m driving it to the mechanic and the shit just popped on me. Get it towed, mechanic says they’re gonna need it till Wednesday. I live two- two and a half hours away by train and bus with a 7:30 start and we leave at 7-8 most days. I barely got enough time to eat when I get home as is, what do yall think?
