I don't think it's a great focus of a manifesto but I'm not adverse to the idea generally. I suppose national saints days are a good starting point and I'd love a November bank holiday.
Thinking about the march/april dates, I'm not too bothered about them being bunched up. Would make Easter childcare a lot easier...
I kind of presumed the bank holidays would be absorbed into the current statutory 28fte, so instead of 20 'bookable' days you'd get 16.
