Daniel Hersh, the acting director of the Lockport General Motors plant, will remain on the job longer than planned, after the man hired to run the plant left the company, according to a GM spokesman.

Konstantinos Katakis, formerly a director of the GM plant in Silao, Mexico, was set to take over the Lockport plant this month. However, last week Katakis left the company to "pursue other interests," said GM spokesman Trevor Thompkins.

Katakis was to be the long-term replacement for director William Tiger, who retired in January. Tiger became plant director in July 2015 and worked with the company for 40 years.

GM has yet to select a replacement for Katakis. Until then, Hersh will remain the acting plant director.

The Lockport plant employs 1,400 and is one of the region's largest employers. The plant produces powertrain cooling, air conditioning and heating products for GMC, Chevrolet, Buick and Cadillac vehicles.
