Shift one works W,Th,F, off the weekend, M, T - then shift two follows to work the same schedule. Anyone in a risk category or at threat of exposure stays home and does what they can through telecommuting.
We're essential communication workers so we've been following this for weeks now and will continue until the quarantine is lifted.
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.
Very interesting.
