Why not? I don't think the parent meant staff should stay on-site forever.
There can be shifts. Staff on shift get tested or even stay isolated for two weeks, then enter the unit, spend a month on-site and leave for home.
Does this sound like a dream job? Not really, I guess.
Does it sound that different from sailors, long-haul drivers, deployed military personnel and many other professionals who stay away from their families for prolonged period of times?
