— February 16, 2018
Excerpt from The New York Times -- "...when employers want to know how good a worker is, they have several alternatives to considering salary history, many of them more revealing. They can, for example, interview the candidate, read letters of recommendation, and talk to former employers and co-workers. In a recent study, the economists John Horton of New York University and Moshe Barach of Georgetown University conducted an experiment on a prominent online freelancing platform and found that employers responded in precisely this way."
