Cast your peepers across this.
Quote from Daily Telegraph 10/11/07:
'Civil servants will be allowed to take bank holidays on Muslim, Hindu or Sikh holy days instead of Christmas it emerged yesterday. Staff at the Department for Childrten, Schools and Families will be given the right to take eight statutory days off each year on the dates of
their choice under new "cultural flexitime" arrangements. The department's offices will
still close on days like Christmas Day and Easter Monday, but the arrangements will mean that it's 2,600 staff can work from home

on those days, and use the equivalent time off to mark their own religous festivals.
Guess that soon it will be the norm. Might also be soon that I will have to become summoner of the mighty Thor. As summoner I shall declare holy days whenever England play a home match and then rough it at home at Christmas, not participating in the prezzies, turkey, good telly etc. of course.
