Before we agreed to employ her, our au pair said she was available for 2 years and arrived at the end of October. I always thought realistically that she would go home after 12 months because that it turned out that that was how long her return ticket is valid for. Last night, she mentioned that her boyfriend has booked a ticket to go home with her so I asked her when he had booked it for. They have apparently booked flights at the start of July.
I'm annoyed because the only reason I found this out was because she let it slip. I feel that she hasn't been entirely honest with us. We paid for half of her flight because we thought she would be here for 2 years and dh has said we should just carry on deducting £10 from her allowance until she goes to recoup more than the 50% that we agreed to pay. Do you think that is unreasonable?
