Amid a flurry of lawsuits and government probes spinning out from Wells Fargo & Co.’s fake-accounts scandal, a group of California plaintiffs lawyers teamed up this week to bring a new employment suit, looking to test out an expanded set of legal theories.

Los Angeles-based lawyer Jonathan Delshad joined forces with a trio of other plaintiffs firms in California—Schonbrun Seplow Harris & Hoffman of Venice, McCracken Stemerman & Holsberry of San Francisco and Pessah Law Group of Los Angeles—to bring a proposed class action on behalf of former Wells Fargo employees.
