Honestly, a pay-cut really only makes sense for people living well out of the area because pay rate is tied to the cost of living of the area. Like someone working in Chicago is gonna get paid more than someone living in the Springfield, IL for the same job. If someone lives across the street from the office building, then adjusting for cost of living makes no sense. Also, a company might have already been paying work-from-home people less before the pandemic because working from home is obviously a perk. I don't really see a problem with adjusting for those things IF, and it's a big fucking IF, the company is honestly adjusting the pay appropriately. Lastly, a pay-cut is a really fucking bad way of making said adjustments.
