Haven't RTFT.
I work shifts on the Tube. We are allocated leave in 5 "periods". All grades are allocated a period, in which the weeks are allocated. You can only change your allocated leave by swapping with a person with those weeks in that period. (Hope that makes sense). So for example, I swapped my P2 Summer leave in September with a colleague who preferred to holiday in September, which is P5.
This results in getting Christmas week off guaranteed every five years.
No services run on Christmas Day so we all take an annual leave day for that, unless our rostered rest days fall on Christmas Day in which situation we get an extra day to use in the New Year.
This year my long weekend in the roster falls on Friday 25th to Monday 28th so I consider myself lucky. The pay-off for that is that I'm on nights from Tuesday 29th, but if I swapped my shifts I'd get a worse deal, only one extra day, for example.
DH is a postie. He has a flexible working arrangement not to work Saturday so he's got the same as me, Friday to Monday off. Locally it was agreed the posties will get Boxing Day off anyway, but they lose an extra day's annual leave.
DH's oldest friend is in the corporate world of property development. He builds massive tower blocks for foreign investors in London. DH got a text last Monday to say his friend will be off work until the 6th January. We had a good laugh about that!
