Office based Mech eng job here…
We can choose between 3 holiday options depending on how many hours extra a week we want to work.
The max was an extra 5 days over the 25 we were getting.
Or we could stick at 25 (I think) or go for 28 days.
I signed up for the highest extra holiday, as I was working the required extra every week anyway.
So, I get 30 days hol with bank hols on top & have to do 38.25hrs/wk to get that.
In typical engineering fashion, the bloke who sits next to me worked out that the mid-option was best in terms of hours worked/holiday earned so signed up to that……but failed to take into account that he too normally works more than the min required to get the full 5 extra days anyway….. 😆
