At the end of 2020, workers at the Ash Grove cement plant in Joliette, Quebec (Canada), were informed that two of the four kilns would be closed, putting at least half of their jobs at risk. Despite the fact that collective bargaining was still ongoing, members of the workplace union Unifor were illegally locked out of the plant on 22 May 2021. Unifor, along with the Quebec Federation of Labor and their members across Quebec, organised a series of solidarity actions.
In response to the union mobilisation, Ash Grove management obtained a new injunction limiting union actions. The employer also filed a CA$2.6 million (about US$2.1 million) management grievance for lost production and equipment breakdown and dismissed two members of Local 177, including a member of the bargaining committee.
Ash Grove cement is owned by CRH Canada, which employs 4,000 people in 100 production facilities. Worldwide, the global giant employs more than 76,000 people in over 3,000 locations in 29 countries.
