SASKATOON, SK, Aug. 7 /PRNewswire-FirstCall/ - Potash Corporation of
Saskatchewan Inc. (PotashCorp) announced that unionized employees at its Allan
Division, Cory Division and Patience Lake Division potash operations commenced
strike action, effective 5:30 p.m. (CST) today. The 487 striking employees are
members of United Steelworkers' (USW) Local 7689 at Allan, USW Local 7458 at
Cory and USW Local 189 at Patience Lake and are responsible for underground
mining operations as well as milling and shipping activities on the surface.
The strike action followed four days of mediation that was unable to resolve
key contract issues, primarily centered on profit-sharing demands by the
union. To date, the union has refused to present the company's final offer to
its membership for a vote.
"While we are disappointed by the decision of union leadership to strike, we
remain committed to operating with a long-term view," said PotashCorp
President and Chief Executive Officer Bill Doyle. "We will manage our assets
responsibly and protect our future cost structure so that we remain
competitive within the global arena. We have offered a top-end contract in the
Saskatchewan market that will make our employees the highest-paid miners in
the North American potash industry. We believe our offer rewards our workers'
important contributions, while protecting the future of our company for all
stakeholders, including our employees."
The bargaining units representing unionized employees at each facility
provided strike notice to the company on July 23, 2008, to which PotashCorp
responded by immediately providing lockout notice. Provision of these notices
enabled both sides to initiate strike action or lockout 48 hours after notices
were served. Previous contracts expired April 30, 2008. PotashCorp has
maintained continuous communication with the USW and the lines of
communication remain open.
