Representatives are elected I don't think that a group of people can be called representatives if they have not been duly elected. The original French did not call this group 'representatives'. They are a group of employees that is expressing a complaint. We do not know if they represent the entire body of employees.

The following describes such situations (in the U.S) and uses the term 'concerted activity'. Perhaps 'concerted activity group' could be a possible translation.

Employees may engage in protected concerted activity in situations other than traditional union organizing and collective bargaining.
“Concerted activity” is any activity by individual employees who are united in pursuit of a common goal. To find an employee’s activity to be “concerted,” the action must be engaged in with or on the authority of other employees, and not solely by and on behalf of the employee himself. An employee’s conduct is not “concerted” unless it is engaged in with or on authority of other employees.
