I'm not going to apologise for my post, nor should Miriam @MrsWonderland. Why are you so triggered by an opinion? Do you have an au pair who you treat badly and this is an uncomfortable read?
I think it's utterly disgusting that someone coming from a position of such priviledge is complaining about someone they've hired, presumably from another country, on a much lower wage, wanting to sit with other humans after they've done their work for the day. This person isn't a random blow-in that they've took in out of pity. They hired her!
I'm also not going to apologise for making a comment about the OP's constant 'exhausted' references. Sorry, during this climate where people are trying to WFH and home school multiple kids, I think it's a bit lost on me. A mum, a dad and an au pair for two babies should really not result in someone being utterly 'exhausted'. Most parents of newborns at the minute have minimal to no support (hence support bubbles for under ones). Most are doing it entirely on their own as they are either single parents or their partner is working. So, perhaps some perspective is needed.
I won't have respect for anyone who thinks that a decent way to treat an au pair is to banish them to their room after they've done their work. Especially in this climate. She can hardly go out and do other things, can she? But, no, she should remain holed up in her bedroom every evening.
There's also the cultural element that other PPs have alluded to. Whereby au pairs work on a lower pay in return for improving their English skills and learning more about the culture, among other things (most of which are unavailable at present). I don't know about you, but if I moved to France (as an example), with an aim of improving my French, it would be a bit redundant me sitting in my bedroom alone every night. I could have done that from my home in the UK.
Treat other humans, as humans, not baby minding and cleaning machines who are to make themselves scare once baby bedtime comes. Au pairs are part of the family, and I certainly wouldn't feel comfortable telling someone that no, they cannot use the communal family space in their downtime. If I want to sprawl out and cuddle my partner, I could always go somewhere, oh, I don't know... that the AP wouldn't go? Like, my bedroom?
But, of course, it's not okay for OP to be expected to go to her bedroom in the evenings. Only the lowly au pair must do that.
Bloody disgusting. Pay for a nanny and a cleaner/housekeeper if you want people to fuck off past 7pm. And pay them their appropriate rates, too. Absolutely fed up with people thinking that their needs are the only needs that matter. The poor girl is probably bored out of her mind and homesick. Does she even have a bedroom that's nice to be in? She could be in a tiny box room with barely room to swing a cat for all we know. Expecting someone to live out of such a small space is criminal.
