on a bit of admin

[Mr.Naom]

Hello everyone!

From The Girl On The Train novel:
" I spent all day in my bedroom, waiting for Cathy to go out so that I could have a drink. She
didn’t. She sat steadfast and unmovable in the living room, (“just catching up on a bit of
admin.”)By late afternoon I couldn’t stand the confinement or the boredom any longer, so I
told her I was going out for a walk."

What the meaning of the red phrase between the brackets?

Thanks a lot!

Which part don't you understand
"to catch up with" catching up/ - WordReference.com Dictionary of English (#23)
or
"admin" admin - WordReference.com Dictionary of English ?

Presumably, she was ‘just getting some administrative tasks done that she’d meant to do previously, but hadn’t had the time for’.

 

[Chasint]

"to catch up" here means to get up-to-date

"to catch up on X" means to get up-to-date with X

"admin" refers to administrative paperwork or tasks

“just catching up on a bit of admin.” = "I'm just getting up to date with my administrative paperwork"

Thanks to all of you.
