The operator of Metro Vancouver’s HandyDART transit system will meet with striking workers and a mediator on Sunday to resolve the dispute that has halted most of the service. The strike, which began after workers rejected a contract offer over pay and staffing issues, has left only essential medical trips available. Union leaders criticize the for-profit company running HandyDART, calling for TransLink to take over the service. Despite the strike’s impact, supporters, including riders, back the workers’ demands for better pay and conditions, hoping for a fair resolution.
