Here is one that comes to mind: The Company will want to modify sick pay.

We will have to provide notes from doctors for use over holidays, days before holidays, days after holidays, days before vacation, weeks before vacation, days after vacation, weeks after vacation, more than 10 hours, less than 10 hours, weekends, or weekdays. You get the idea.

There are lots of other possibilities. The Company will be creative and shameless in their "needs."
