Not only is their food bad, but they mistreat their workers, too!

Individual Subway franchisees have been found in violation of pay and hour rules in more than 1,100 investigations spanning from 2000 to 2013, according to a CNNMoney analysis of data collected by the Department of Labor's Wage and Hour Division.

Each investigation can lead to multiple violations and fines. Combined, these cases found about 17,000 Fair Labor Standards Act violations and resulted in franchisees having to reimburse Subway workers more than $3.8 million over the years.

Out of all the fast food chains in America, Subway is the worst in labor violations. Think about that for a minute.
