Attorney General Chris Koster says David Mollohan, operator of M & D Excavating, was sentenced to a 60-day suspended jail sentence, two years of court-supervised probation, a fine of $500.
Mollohan will also be placed on Missouri's contractor debarment list for one year. That means he and his company cannot contract directly or indirectly with any public body for the construction of any public works for that period of time.
Mollohan is the 16th contractor to be put on the debarment list since 1992, and the sixth to have been prosecuted by Koster.
Mollohan has repaid more than $41,000 in full restitution to the 14 workers.
The Missouri Labor Department's Division of Labor Standards referred the case to the Attorney General following an investigation.
