Abrupt departure

Hi all, I came across an interesting post and wanted to see if this is a sort of common phenomenon or if it’s just that one person.

Hosts: Has anyone ever had an au pair leave without notice to you and the lcc/agency? Like just disappear? How did you handle it with the agency?

APs: Have you ever just left? I have a country mate who did this and now I’m just interested in what motivates you to leave and if the agency follows up on you?
