What is it called…

[BigYellowTaxiT]

…when someone says things like “[manager’s name] said you have to” when they’re trying to make you do additional work compared to everyone else.

Or putting your name down to do additional work compared to everyone else without asking you and just presuming you will do it.

Or private messaging you to make you do extra work instead of asking you in the team chat?

it’s not gaslighting but is there another word for this kind of thing?

Taking the piss

😂

Bullying or victimisation

As whatever00 said its called taking the piss...
I know what you mean tbough and it probably should have a specific name....
Workplace cfery....

Lying through their arse
Childish (my mum said)
Bollocks

I’m autistic so am rubbish at advocating for myself and/or recognising when I’m being taking advantage of.

Exploitation

This ^^

Appropriation of manager's authority to coerce you into doing what they want you to do.(Not the snappier definition I grant you. Coercion would probably do.)

No-one should be putting your name down to do extra work ?????
