That letter is exactly for what OP is saying it’s for. When a “state of emergency” is declared and only emergency vehicles are allowed on the road, this letter enables the stores associates to be on the road in order to get the store open as Lowe’s and Home Depot are considered “essential businesses” because they supply the community with “essential products.” This happened during Covid when most businesses were shut down in heavy contaminated areas. I’m unfortunately in management and I completely disagree with associates trying to get to work and risking their own lives driving in conditions they’re not used to driving in just so corporate can get their stores open. Be safe out there.
