If my days off aren't allowed to change on a whim, I'll do this. But right now I am still holding out hope that my group will let us pick our days off and remain flexible to change them each week as long as we're in 3 days. If I get that flexibility, my regular days in will be Monday, Tuesday, and Wednesday. This way if there's a bad accident or storm in the morning, I can in the moment swap that day off and go in Thursday (and if it happens twice in that week, Friday as well.)
Where I live, there is only one road between my town and work. So if there's an accident, there is no choice but to sit in the backup for hours to get to the office. So cross your fingers for me!
(And yes, I realize that some groups already know for their LOB that kind of flexibility won't be allowed, but we all know different LOBs will have differing levels of flexibility around RTO.)
