How do economists measure the quality of new job creation, not just quantity?

The unemployment rate gets cited constantly, but I'm curious about how economists think about the quality of new jobs being added. If a country replaces 100 manufacturing jobs with 150 gig economy or part-time retail positions, standard metrics might show employment improving. But are there established ways to measure whether net job growth is actually moving the economy toward better outcomes? I'm interested in frameworks for assessing job quality over time, not just raw numbers. Please point me to relevant research if possible.
