I have always applied the unofficial policy that if an employer needs me in an 'emergency' (ie. to do something at short notice when I wouldn't otherwise be working for them), then I will do it, but will round up the time rather generously and take that amount of extra time off elsewhere.

For example, boss calls interrupting my sunbathing session needing advice on how to fix something. Call is 14 minutes. I'm going to either bill that as an hour, or take another hour off sometime.

Doesn't apply if its because I've done my job badly (ie. didn't properly document some procedure, so now someone else needs help following it).
