I'm dead against it, in the same way that I don't like Sunday trading and calling Christmas 'xmas' etc. etc..
I think it undermines society, not that it hasn't been undermined already over the last forty years, and I think it looks like those who do work are a bit sad and shold enjoy the time away from work, with other people and try to have something different in thier lives, not more work work work.
The only things working on Sundays and bank hols etc are the emergency services and a cut down tv and radio network.
No, I never work BH's.
