Cessna Aircraft Company, the Wichita-based aviation manufacturer with an assembly plant in Independence, will slash its total work force by another 1,300 people, the company told employees this morning.

Including the cuts announced today, Cessna has cut staffing by 8,200 people since November.  It’s unknown exactly how many employees from the Independence plant have been given pink slips or how many of the Independence-based workers will be impacted by the most-recent round of job cuts.

Layoff notices will be distributed to 800 employees, primarily hourly workers on the production lines, on June 19, Cessna spokesman Bob Stangarone said. The 60-day notices will be distributed before the start of a four-week furlough.

The remaining notices to about 500 people will be issued no later than August 14, the company said.

In addition to the four-week furlough, the company is adding another three weeks of furlough. Production employees will not be affected by the additional time, Stangarone said.

The three weeks will be scheduled with the individual employees between now and the end of the year, Stangarone said.

Cessna, which at the end of 2008 had planned to deliver 535 jets this year, has revised production downward four times since November as the company experiences order cancellations and delays.
