Chat on another thread reminded me of an old boss I had.
She insisted everyone had to be in the tea club. I don’t drink tea or coffee and I’m allergic to milk so declined.
At that time another new start declined to join the tea club and the HT actually sent out an email detailing her disappointment that “some people” had opted out of the “collective enjoyment” of the tea club. A few months down the line she told me she’d cried at the “snubbing” of the group.
I worked there three days a fortnight, and I was also PT in three other schools over the fortnight, so four tea clubs I didn’t use would have been bloody expensive!
