Dollar General has paid a fraction of the $21 million it owes in fines for hazardous working conditions

• Dollar General has paid less than one-fifth of the $21 million in fines it owes OSHA.
• The retailer has accumulated the fines over several years due to messy and chaotic stores.
• The problem is so bad that OSHA labeled the company a "severe violator" earlier this year.

Dollar General has racked up $21 million in fines over hazardous working environments in its stores. But so far, the company has paid just $4 million of what it owes.
