I mean it doesn’t sound like they’re seeking ‘extra’ work, because Anon is not doing any work at all. I’d argue there’s a difference between ‘extra work’ and ‘any work’.

They’re not meeting expectations either because the expectation for their role is unlikely to be ‘doing fuck all’, the expectation is doing whatever job is outlined in their JD, which they’re demonstrably not.

Again, I don’t really care either way. Do what you can get away with, but be cognisant of the risks, and how that might affect your future employability otherwise you may find yourself doing nothing because you don’t have a job at all.
