Got my bonus via check, but I work too much to have time to cash it.

I go into work at 7:00 am before the bank opens and I'm out around 5:00 pm when the banks close. Got my bonus last Monday via check cause my boss wanted to physically hand us the checks . I was so tired from working my ass off Friday that I slept in until noon Saturday. I have no idea when I'll be able to cash this thing! I use a small credit union that doesn't do mobile deposit
