Recent Experience

Red Chris Development Company Ltd. v United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, Local 1-1937, BCLRB No. B25/2018

Where the Board awarded the union a second access order to a remote mining camp for the purposes of organizing workers who reside on the employer’s property. The Board also ordered that the employer either disable or cover up the security cameras that would otherwise capture the areas in which the union was conducting its organizing drive. In reaching this decision, the Board reasoned that workers should be entitled to interact with union organizers without fear of employer surveillance.
