If you’re going to force everyone into the office five days a week, can you at least turn the heat on? People are sitting at their desks in coats, winter hats, and gloves. That’s not exaggeration either.
You made the RTO decision, not employees. If the company doesn’t want to pay to make the buildings habitable, then revert the policy. Forcing people to commute just to freeze inside an office is beyond ridiculous and completely self-inflicted.
