RIO DE JANEIRO, July 30 (Reuters) - Embraer said on Monday it will defend itself against a lawsuit seeking to suspend the Brazilian planemaker's negotiations with Boeing over a proposed takeover of most of Embraer's commercial jet unit.

A Brazilian labor judge this month rejected a call to make the proposed acquisition dependent on a pledge to preserve all local jobs at the company. (Reporting by Alexandra Alper; Editing by Sandra Maler)
