To expect my working from home to be respected

Could you put a sign in the door when you are in a meeting? (My husband does this). Then the understanding is he doesn't come in when the sign is up, but acceptable at other times (though a knock appreciated)

Actually, companies can stipulate quite a lot (although it’s good that your employer doesn’t assume young workers have additional office space at home).

My employer requires me to have a separate, private and quiet place in order to work from home (and working from home is a requirement). We are not allowed to be looking after children or elderly relatives at the same time. Barking, interrupting dogs would be frowned upon. I think retired people do not understand this about working from home. The father could potentially affect his daughter’s employment if his disturbance affects her ability to line manage or if he caused a break in client confidentiality.

You're question was " AIBU to expect my working from home to be respected"

YABU to expect.

I would be very grateful to be living at home and saving money in my mid 20s and given another room just for^ work.
You're very lucky and hopefully you show appreciation to your dad that you moan about.^

Why are you so determined to think bad of the OP, why can't her father be a belligerent little tit of a man without your little PA remarks about the OP being the same?

I'm from a different generation too but I'm aware how life has changed in the workplace/for younger people.

Are you saying WFH per se isn't ideal, or that it isn't ideal in OP's situation, btw?

Yes. That doesn’t tell us whether OP is similar to her father or not, though.

We do know from the OP though, that after having the problem explained, the father deliberately barged in a third time just to make a point. Then refused the OP's request to discuss it properly and see if they could come to a compromise they'd both be happy with.

So right or wrong, the father's a belligerent little tit of a man. We know that for sure.

Yes, possibly.
On the other hand, living at home with your parents at "mid twenties" isn't ideal, neither
is "working from home".
However, I'm a different generation.

Get one of those rubber door wedges. Cheap as chips. Block door with it so that he can’t push it open and come in. Wear headphones so you can’t hear him shouting. My DH does the same. This works.

Then companies have to make allowances for their employees not working from a professional environment. You can’t have it both ways. We have space for our junior colleagues because they usually only have their bedrooms to work from - it’s not healthy to be stuck in one room.

How do you get "sweeping generalisations"
I opened by saying it depends and the sentence about the 90s said most parents not all.

Maybe it's you that shouldn't make sweeping generalisations when your situation or experience clearly isn't the same as everyone's.

I think it depends how well you get on with your parents.
My son acts like an entitled brat in his mid 20s shows no respect, is a misogynist, rude, doesn't do anything asked of him or anything around the house and leaves a mess every time he's in, he's lippy, moody and resents living here and we resent he's still here. He's is a royal pain in the bum.

I can't wait for him to move out and the only thing that makes it bearable is that he's out at work all day, I think I'd have break down if he announced he would be home all day and going to be taking over my office.
By the time I was his age he was 9 I was married and had a left my parents house over 10 years, many parents had children in the late 90s expecting them to be long gone by now but instead they are they stuck with these grown men/woman who seem to think they can call all the shots and make all the boundaries while mum and dad to the line.
No wonder this generation aren't having children they don't fancy what's in store.
