Driver's Hours And Yard Practices

Darkside:
To be fair the OP is the kind of nightmare employee that has made her like she is.

It’s her yard she can ask you to do what she wants, though whether you do it or leave is up to you…

Emailing DVSA and HSE for answers, instead of going to the people above her and asking■■? Not getting the answers wanted so coming on here for moral support from other drivers■■?

Industry is full of snowflakes nowadays…

As I read it, the new transport manager is the only person there who knows anything about transport? Guessing it’s own account?
There is no one above her who could correct her.
Asking DVSA for clarifications seems reasonable to me, but asking for an investigation wouldn’t.
