My employer (a university) has a mask mandate - we must wear masks in the vast majority of circumstances at work.
I abide by this.
Today I was in Tesco which is not on campus without a mask. I saw my line manager but we didn't stop to speak (heading in different directions, some distance from each other).
Then I had received an email booking in a meeting to chat about my not wearing a mask in Tesco.
The email basically said that staff are 'expected and encouraged' to wear masks in enclosed spaces such as shops. That we should model good behaviour to show our care for the local community and to encourage our students to also wear masks which in turn shows their care for the local community and each other.
I'm really pissed off but before the meeting, I want to check that my employ can't mandate mask-wearing by staff outside of work, right?
