The AppStore wants my work appleID to update

The screenshot refers to the Apple Store app, not your App Store. Delete the "Apple Store" app. This was downloaded with your work Apple Account. You cannot delete the App Store, but you can delete the Apple Store app. These are 2 completely different apps.

I do not recommend a restore in this case as it will try to redownload the Apple Store app and you will see the same message.

I think that worked! I deleted both (one o guess is just removing it from the Home Screen) and when I replaced the App Store app it no longer had it itself in the list of apps to update so I’m hoping it will allow me to update under my personal id next time around. Many thanks all!!!!

Yep, that will do it. Any other app that was downloaded with your work Account will pop up the same message when there is an update available for that app, but all you need to do is delete the app and it will no longer attempt to update. Unfortunately, there is not a good way to identify which apps were downloaded with your work account in advance.
