It’s always tough to watch beautiful stain grade hardwood get covered up just because the current trend is “grey everything.” Honestly, those natural finishes tend to age better than the paint fads you see on HGTV. That said, if the higher-ups are set on it, the best you can do is make sure the job is done really well so it doesn’t look cheap or rushed. I went through a similar situation at my office and we brought in professional interior painting services, and at least that way the end result looked polished and intentional rather than a quick flip. Sometimes you just have to roll with it, even if it hurts a little to cover up quality materials.
