Give over, telling them to sit x amount of coaches away from the main part where they work? If you would like to furnish me with the posts about all these people complaining about being unable to sit in those back 3 seats, when others are freely available then I’ll also tell them too. There’s up to 4 coaches of first class seats and when the train is not full, they’re entitled to a break, the same as anyone else. They obviously won’t sit there if the train is full. Hopefully for the staff, this will be recognised during the refurb and this can finally be put to bed.
It's not, with quite a number of crews, only the back row (which I believe is now formally allocated to them on the displays). They actively discourage you from sitting in coach K.
It
doesn't matter if the train is full or not. Other than that row, they are available First Class seats, not a messroom. Passengers are entitled to choose their seat from those which are not reserved and do not have a backside sat in them at the time they wish to choose one.
Yes, I too hope this is recognised during the refurb, with the provision of a segregated staff rest area, which will finally solve this issue which has been going on for years (and also more single seats, so they are not as prized and people who want them can easily get them).
As for where to sit, it's at most a couple of hundred metres away. In many businesses, break rooms are a reasonable distance from the work.
