I just saw this: Dems Stake Out Their Turf With Bill Targeting Epic Systems. Law360 reports that Representatives from New York and Virginia have introduced a bill (H.R 7109)in Congress that would ban class action waiver provisions and requirements to settle disputes only by arbitration in employment contracts. The Senate is working on a similar bill, according to the article, but doesn't have any information on that.
Further bulletins as events warrant.
