If these supervisors are CWA union members then I think they should cool their jets and understand the situation and not hassle a fellow union brother...Its one thing if a manager is gonna go in and hassle you but a fellow union supvr who is well aware of the shortages and pressures that are part of you job 3 extra minutes is not gonna take the phone lines down...consider letting the union know if these fellow supvrs are harassing you because they need to understand that any action taken for this treatment could backfire on them....You dont need the BS..were getting enough if it already without their help.....
