The NLRB San Francisco division ruled earlier this week that the Jack-In-The-Box, Inc. arbitration agreement violates the National Labor Relations Act in that as a requirement of employment, it inhibits an employee’s ability to bring a class action suit.   NLRB administrative Judge Mary Miller Cracraft recommends that the provision be either revised or rescinded.  A spokesman for San Diego based Jack-In-The-Box said the company has every intention of appealing the decision.
