SANTIAGO, Chile, Oct. 20, 2000—Chile’s biggest electricity distributor has signed a four-year collective contract with two unions ahead of schedule, the company reported.

Chilectra’s contract, which runs from Jan. 1, 2001, through Dec. 31, 2004, makes benefits the same for Union No. 2 and Union No. 5 by improving the areas where they differed, it said in a statement.

The two unions represent about 500 workers, it said.

Chilectra originally was supposed to start negotiations with the unions in the second half of November, it said.

Chilectra is controlled by Chilean-based power conglomerate Enersis, which is controlled by Spanish utility Endesa.
