I manage teams in multiple locations with employees who have different FOW statuses (even within same team). Looking through Workday, it appears that the pay range for employees who are in-office is a fair amount higher than those who are slated as WFH tied to the same location, up to 10% or so. This doesn't mean that they are necessarily paid higher right now, but their potential is a lot stronger. Didn't HR say that FOW status doesn't mean you will have more or less opportunities, everyone is the same? It also looks like pay ranges are higher in high cost-of-living areas, though I thought they said that they were going to flatten that at some point.
I know that there were a lot of issues when they released the pay ranges for everyone a few years ago (they took that out quickly lol) as many people saw that they weren't even near midpoint or some were not even in the range, so perhaps this just another case of HR saying one thing and doing another?
