That depends on you and a little seniority.
Traditional schedule is 7 days on and 7 days off, so that's 6 nights away from home in a row.
You can work more or less and spend more or less nights away from home. The least (or best) schedule can offer at minimum 4 nights away from home in a row.
Our new CBA (assuming it passes) rewards those financially who spend more time in a row away from home, unfortunately.
The more days you work and the more days you work in a row, the more you make.
Good luck.
