I’ve hired two ladies to clean my house for two hours every fortnight. They work as a team and do a good job.
My issue is that they always leave 5-10 minutes early. If it was one cleaner I don’t think I’d mind as much. But with two it’s up to 20 minutes that I’m paying for and not benefitting from. There’s always something left undone (presumably because they’ve run out of time). This week it was the stairs and the corridor. So it’s not the case that they’re leaving because they’ve run out of things to do.
They seem nice and reliable, so I haven’t said anything. But in three months they’ve never stayed for two hours, yet expect full payment.
YABU - this is the norm, don’t bring it up
YANBU - say something (I hate confrontation so if I do, I’ll probably have to find someone else as I won’t be comfortable with them afterwards.)
