Comment 2 for bug 1969641

I have tested this and it works for the Angular staff catalog, but before I sign off I wonder if it would be better to do this check / alert immediately upon login?

I ask because the patron registration/edit form will not load without a working location either - I don't know if there are others.

We assign working locations to all staff, but are there libraries that have types of staff that legitimately do not need working locations?
