Cherrybim,
In my field its not usually an issue, except on emergency projects. They tend not to assign those to me unless they don’t need me friday night and saturday. I show up saturday night as needed.
But they still appreciate the Christmas holiday season and knowing someone is there. There is a lot more competition for Christmas week than friday afternoon.
Incidentally, my husband is off Christmas week (his company closes) so it would be nice to be off, but alas…
