FFs work 24 hour shifts, very other day for 3 days then have 4 days off and it starts again. It is tough for young families with or without children, You miss a lot of events and the spouses pick up a heavy load. 2% is okay but the other step increase help a lot. 40 years ago most would have a part time job to keep up with inflation. I think a lot of them still do. Its a great job but not everyone can be away from family that much.
