SAO PAULO, Sept 17 (Reuters) - Metalworkers at Brazilian

planemaker Embraer ( ERJ ) went on strike on Wednesday for an

indefinite time, demanding wage increases and the signing of a

collective labor agreement, the Metal Workers Union from Sao

Jose dos Campos said in a statement.

Embraer ( ERJ ) did not immediately respond to a request for

comment.

According to the union, Fiesp - which is the entity

representing the aerospace sector - proposed in negotiations a

salary adjustment only based on inflation and a reduction in job

stability for injured workers and those with occupational

diseases.

That proposal was rejected last week and a strike notice was

approved, the union added in a statement on its website.
