The operator of five Wing Stop franchise locations in Mississippi faces fines and was ordered to pay back wages after the U.S. Department of Labor found several violations.Boss Wings Enterprises LLC in Southaven operates Wing Stop locations in Clarksdale, Tupelo, Starkville, Olive Branch and Oxford. The Labor Department's Wage and Hour Division investigation found that franchise employees had to pay for their uniforms, safety training, background checks and cash register shortages that caused some employees' average hourly rates to fall below the $7.25 federal minimum wage.The investigation also found "overtime violations when the employer's deductions for safety training and background checks illegally decreased the rate-of-pay in weeks when workers earned overtime and led Boss Wings to pay overtime at rates lower than federal law requires," the department said in a new release.Division investigators also found that Boss Wings allowed a 15-year-old employee to work past 10 p.m. several times in June 2021, which is a violation of child labor regulations.Boss Wings paid $51,674 in back wages and liquidated damages for 244 workers as a result of the findings. The company also paid $62,753 in civil penalties, the department said.
