Arbitration agreements are a common tool many employers use as an alternative to going to court to resolve disputes with their employees. Arbitration has the potential to be a faster, cheaper, and more private way to resolve disputes, with more finality. One of the biggest advantages many employers see in arbitration is the ability to resolve disputes individually rather than as part of a class action. However, the NLRB has determined that, in its opinion, these waivers violate employees' right under federal labor law to engage in "concerted activities" for their "mutual aid or protection." This has caused uncertainty as to the legality of such class action waivers in arbitration agreements in the employment arena.
