A staunch advocate of workers’ rights, Lynnfield, Mass., lawyer Frederick T. Golder saw an opportunity to be trained as a trainer in his field — and he ran with it.

In the first-ever program established by the Massachusetts Commission Against Discrimination (MCAD), Golder and about 50 lawyers and other professionals are participating in a seven-day program aimed at teaching them how to instruct businesses about discrimination laws and how to prevent harassment and other forms of discrimination in the workplace.
