The truckload carrier will most likely see its 250 employees laid off, including drivers and administrative and service personnel.
Richard Sitton, president and CEO, told the Journal he wasn't sure how the closing would play out, but that it would be a smooth liquidation.
If the company lays off more than 50 employees, the state of Missouri's Rapid Response program kicks in along with the Division of Workforce Development, the news service reported. The Workforce Investment Board will start helping the company's employees as soon as possible.
Sitton Motor Lines was founded in 1979 by David Sitton and his two sons, Richard and Michael. The company started out serving 13 states with five owner-operator tractors and 50 new trailers.
Sitton, a privately held corporation, operates as an irregular route common and contract carrier, providing truckload transportation service throughout the U.S.
