3rd and 1st shift are the same thing..
depends on if you sleep before or after your shift.
when i was on 3rds i worked 11pm-7am slept 8am-3pm. then had my day open from 3pm-11pm.. my buddies were sleeping when i was working, and i was sleeping when they were working. the other 7ish hours of the day was open, just like the people on 1st..
it's 2nd shift that eats your life.
