General Electric Company's (GE) jet-engine unit seeks to reduce its management staff by more than 1,000 workers this year, a company spokesman said Thursday. The layoffs would come from a total of 16,000 salaried employees, GE Aviation spokesman Rick Kennedy said in Boston, Massachusetts. The world's biggest jet-engine maker does not plan to reduce its manufacturing workers. “This is the most difficult year for anyone in aviation to try to forecast,” Kennedy said, citing the global financial crisis.
