Neither Peter nor Mary will do their work unless their mother sits at the table with them.

Since you use 'their" before "mother", you might as well use it before "work".

HI
It is more customary to use "their" especially when you use "his or her" repetitively in a text.

Yes. It is very common to use "their" as a gender-neutral pronoun, even in the singular.
