My boss said "working from home isn't actually working"

My boss complained about a company we partner with because they're only in office one day a week, claiming they're not really working.

I just find this mentality so exhausting. I get chastised for working from home while sick, despite the fact that the company put out a note asking for employees to stay home if they're sick.

There is no pleasing this woman. I hate her for making me feel guilty about taking care of myself.
