SANTIAGO, Sept 22 (Reuters) - Workers at Escondida, the world's biggest copper mine, went on strike for 24 hours on Monday, calling the stoppage a "warning" as they seek improved working conditions.

The mine's powerful union had said last week it would call out its workers for 24 hours on Monday and again on Wednesday after it failed to reach agreement with management over issues related to working hours, health and safety.

The strike followed "a null result from talks with the company," the union head, Patricio Tapia, told Reuters on Monday.

Escondida is controlled by global miner BHP Billiton , while Rio Tinto also owns a 30 percent stake.

BHP did not immediately comment on the strike.
