Can my spouse work in Luxembourg after arriving through family reunification?

One advantage of the Luxembourg family reunification permit is that it grants the right to work. A spouse, partner or eligible family member who receives a residence permit on this basis may take up employment or start a self-employed activity in the country.

This means your family members do not have to go through the separate salaried-worker authorisation and ADEM vacancy process that other newcomers face. The work right is tied to holding a valid family-member residence permit, so it is important to keep that permit renewed and in order.
