Employers that had not signed an arbitration agreement between an employee and a related company could not enforce the agreement, a California appeals court ruled.
The employee worked for seven related companies, all of which shared office space in the same building. Only one company entered into an arbitration agreement with the employee. The other six were legally separate from the one that had signed the agreement, but in addition to sharing office space, all the companies shared payroll, human resources, and legal and risk management teams.
