The only rules in the US are when there are state employee laws. Some states are "at will" and you can quit or be fired with no particular reason. Some have much stricter rules.

There was a big deal in France about allowing under 25 year olds to be fired with no reason in their 1st 2 years. This was supposed to make people more interested in hiring them. Instead they just got pissed off. I'm not sure what the rules are in France but there must be some sort of labor laws.

Of course, none of this applies to England and I would suspect that she called in "sick" after one too many nights out on the town.
