The total impact on Wichita's workforce remains unknown, but the Securities and Exchange Commission (SEC) Thursday confirms with Eyewitness News that by the end of the year, Textron will reduce its headcount at the company by about 875 employees.

With Textron Aviation, Textron is one of Wichita's biggest employers with about 10,000 workers. While it's unclear how many layoffs will specifically happen in Wichita, the company confirmed the majority of the layoffs are in the city. Wichita is the company's headquarters.

In the SEC filing, the company says the layoffs primarily reflect the completion of the Longitude jet certification. Textron says positions primarily impacted by the layoffs include engineering and additional support functions.

The company offered some employees severance packages. The SEC filing shows severances totaling more than $40 million.

Jerry Bonson, an engineer technologist, is among the Wichita workers being laid off. For the first time in decades, he's unemployed after spending 25 years with the company.

"We didn't expect it. I was aware of people talking about layoffs and all. I didn't expect it to hit us," Bonson says. "I worked in experimental and that's always been fairly safe, but this time, they just hit everywhere."

The news comes three weeks before Christmas and just days after doctors discovered Bonson's wife has a tumor. Results from recent testing should soon determine if Ilene Thompson as thyroid cancer.

Jerry Bonson says his family is one of many in Wichita affected by the layoffs.
