And plumbers and electricians and linemen...

On another thread someone said - it may have been RabbiSol - that in Orthodox Jewry one cannot volunteer to work on someone else's religious holiday if it falls on a day that one also holds sacred. (If I understood it correctly)

But in Oregon there is a Jewish community that steps in and takes the place on the job of many people who celebrate Christmas, which I think is exceedingly nice. They may have been from the 'ReformED Jew (as a dearly departed person once said) branch.
