I'm no fan of First group
No, you're opening posts have made that pretty clear!
Regarding the poster, like Ollie, it's not one I remember seeing - and a quick check of two booking on points and I can't see one up at either.
There's some (very) recent posters up about bullying, harassment and so on but no phone number - just advice to speak to you manager,
HR▸ department or union rep.
All staff receive a Care First booklet and quick reference card offering assistance should they need it, and a different telephone number to the one you refer to that is presumably still valid. I see no need to reprint it here though.
In addition, drivers receive booklets giving advice on how to handle a fatality, which is company and union endorsed.
My experience is that
FGW▸ care about their staff far more than many companies, though in general all large companies (both in and out of the railway industry) have bucked their ideas up in that regard over the last few years.
I can only assume this poster you speak of is an old one that might still be displayed due to the local manager being responsible not removing it from the notice board?
