N/c for this. I’m self employed and work in people’s houses as a housekeeper. I took on a young family and don’t often see them as they’re at work. However I’ve had a few encounters with the husband when he’s been home looking after their child.
On the first occasion I was working in one of the rooms and he appeared with their child and told me he was watching me work. He stood a few feet away and stared chatting to his son. I was bending over and aware he was able to stare down my top. So I ignored him and started hoovering which prompted him to leave the room.
Half an hour later he started to do this again in a different part of the house. So I broke off from that task and moved to an area where he couldn’t follow me.
On a separate occasion I was working upstairs at the end of the corridor and he decided to sit in the room opposite with the door open and kept staring at me without saying anything. Again I ignored him.
YABU to feel concerned about his behaviour
YANBU to feel uncomfortable/concerned and give notice to leave
