My son’s job is like that. He has an essential job with a satellite mission at NASA. They can only go in for essential mission work and otherwise work from home. He’s one of only a small number who can do his particular job so they are on an on-call schedule so they never are together.
It’s a lot more work when there since we’re essentially working at half staff but the seven day stretches off are very nice. The workaholics are getting lots of quality time with their families, some of them for the first time ever.
