Potash Corp union to initiate rotating strikes

TORONTO, July 25 (Reuters) - The union representing about 500 workers at three Potash Corp of Saskatchewan (POT.TO: Quote, Profile, Research, Stock Buzz) mines said on Friday its members will start limited job action to press the company on contract talks.

The United Steelworkers said its members will not work any overtime and would soon start rotating strikes, though they will not shut down production.

The two sides have been unable to reach a new contract since the previous agreement expired in late April. The union is now in a legal position to strike and the company is in a legal position to lock out employees. (Reporting by John McCrank; editing by Rob Wilson)
