To think a 4am start every day is unreasonable?

[tinyissues]

DD has a relatively new job which is her first job relating to her degree (has been doing it 3 months).

Issue is it's a 4am start every Monday-Friday! She's such a night owl, so is going to bed at 11pm every night, to get up for 3...

I'm worried she is literally knocking years off her life. She admits she is really tired but just catches up on weekends or takes a nap after work.

AIBU to think this isn't a sustainable job and she needs to find something else?

It's 4-1pm as well so quite long

If she’s a night owl just go to bed earlier isn’t a solution. Probably 4 hours and a nap suits her better. She’ll find her own way. She’s an adult.

If she stops napping, eats earlier and goes to bed early her clock will adjust. She is only a night owl because she has trained her clock to be with her habits. Her new job needs new habits.

If she is going to her job half asleep she will not succeed at it and be able to move onto something better with more socialable hours after a couple of years.

I’m a night owl, always have been. If I went to bed early I’d just lie awake. She’s an adult it’s up to her how she manages her sleep. Lots of shift workers sleep in chunks.
I have a night owl teen - always has been.
I leave her to it as my biggest source of conflict as a teen was my early riser mum having a go at me. She goes to bed 9.30/10pm and thinks everyone else should.
I can see why going to bed at 7 or 8pm isn’t appealing to a 22 yr old. If she sleeps 4 hours and naps in afternoon she’ll still be able to socialise with friends in early evening.
