AIBU for refusing to reschedule my interview again for my mum?

This ^

I'm wondering if the OP has told her mum at all.

And why couldn't/can't mum rearrange her hospital appointment?

In that situation my Mum wouldn’t even have asked.

Have you actually spoken to your mum @TooLateToChange and actually told her how important this is and you can't postpone again? Surely, she will be understanding if you explain fully? You really can't miss this, it would give a very bad impression if you postponed twice. Surely, your mother would understand?

I wouldn't have rescheduled it for an adult child either (obviously depending if they have additional needs/it's very serious) so your mum might feel that if hers is potentially serious, then there is no difference.
But it's true that missing an interview might well be a red flag for employers, especially in this economy.

I can’t imagine they’d think you a good prospective employee if you reschedule your interview a second time. Your mum is being ridiculous.

This - once is fine, but if you have so many ‘family commitments’ you cannot make the interview twice, they will make inferences and it could damage your chances. Sadly, according a newspaper article today, women really do pay a parent tax when it comes to employment opportunities. Suggest she reschedules her appointment instead or takes someone else.

Your mum is being completely unreasonable you need to set proper afult boundaries with her or this will only get worse as she ages.

Definitely YANBU

Don’t cancel for this as it will make you look very flakey. Quite likely the job won’t reschedule again anyway.

The fact you’ve already cancelled once is a reason not to do it again, not a reason to do so.

And a child (even an adult child) is vastly different to a parent, especially when the parent has other options.

Ask her to use her phone to record the meeting.

Your Mum is being extraordinarily selfish. Is she usually like this? She sounds insufferably self-absorbed. Please don’t postpone again.

I understand accompanying a son or a daughter to an appointment regardless of what age they are - sometimes the doctors might ask a question that the parent knows the answer better than the kid.
But your mum is a bit different, and you don't want to lose this job opportunity. She can always take notes in the appointment or ask the doctor to write things down for her if she thinks she'll forget any details.

OP, dont reschedule, cos it may as well mean you dont want the job in the first place

Does she not want you to take this job? I can’t imagine my parents trying to sabotage a job interview like this.

Tell her to reschedule her appointment, ask someone else or arrange a taxi.

Exactly, not a good indication that you want the job.

No way would I have rescheduled once, let alone twice! What will happen if you get the job, will you still be wanting time off to ferry people about?!

Anybody can have a conflict with the first date that is given to them, so rescheduling once is fine, but to reschedule twice makes you look totally unreliable and really tells them where you would place work in terms of your priorities.

agree with this unless it was life or death.
And neither would I have asked my mum to, unless literally it was for something requiring surgery, cancer or similar.

Absolutely do not, unless you want to be binned off.

How selfish of your mother.
Has she form?

I wouldn't hire someone who reschedule twice - other than extreme circumances with proof thst something was beyond their control - dead of close relative, serious injury etc.

I used to interview people a lot. Someone who rescheduled twice would come across as potentially unreliable. They would have to be perfection incarnate to get the job.

Strongly disagree.
It's worth establishing boundaries sooner rather than later. OP's mum is being ridiculous and selfish, and this is not going to improve if OP indulges it.

Even if they agree to reschedule it they'll be thinking bloody hell if she can't attend a interview on the alloted day , twice, what will she be like if she works here? You'll blow your chances for sure.

I just couldn’t be bothered with the drama this would cause. A breezy “sorry couldn’t change it mum” is all it takes.

Also. Why doesn't she just reschedule her own appointment? Every time I get an appointment, even for something important, there's always a phone number to ring to reschedule.

Yes. Emotional Blackmail. Been there. Done that.

And very selfish to try to get you to put your job opportunity at risk, which it would..

For similar pressing reasons (with four siblings who were always getting DM to do chores for them and DM's own siblings nearby)
I had to refuse a command and offered to pay for her taxi there and back to stop the blackmail.
She refused of course and took great enjoyment in telling anyone who would listen how "heartless" I was, (without mentioning the taxi offer of course)

It sounds as if you would help her with urgent things,
but when she's being ridiculous as she is in this case, you have to say no so she gets used to the idea that you are not her only and always option, and her other options get used to being called on too
or the game will just continue.

And as pps have said. Child trumps parent. Sounds like she's jealous of the care and attention you give your DD. Says a lot about your DM's character that does.
