The Alberta Labour Relations Board is now deliberating whether to grant an injunction ordering correctional guards back to work immediately. Seven Alberta correctional facilities are in lockdown mode today after guards walked out across the province overnight. The executive director of the Edmonton Remand Centre and director of the Fort Saskatchewan Correctional Centre have now testified at the hearing in Edmonton which will determine whether an injunction filed by Justice Minister Jonathan Denis goes forward. "Our first priority is ensuring public safety and security," the minister said in a release sent late Friday night. "Any threats to public safety are dealt with swiftly and seriously by this government," he said, adding that the province will be conducting a full investigation of the walkout. “Contingency plans are in place and being implemented as needed." Although the province wanted the application for injunction to extend to all institutions across the province, the labour board has ruled today's hearing will only apply to the Edmonton Remand Centre and Fort Saskatchewan Correctional Centre. All other institutions must be given notice at least four hours' notice before a second hearing on the work action can be held. Should the injunction go forward, union vice president Carrie-Lynn Rusznak says workers need to see whether the province has made any concessions regarding safety issues. If there is a back-to-work order, workers will decide for themselves whether or not to return to work. The job action started at the new Edmonton Remand Centre on Friday when corrections officers responsible for staffing the afternoon shift refused to report for duty. The board will reconvene at 12:45 P.M.MT.
