The US Department of Labor found a West Columbia home healthcare provider shortchanged 36 employees who provide companionship and personal care for seniors, people with cognitive disorders, mothers of newborns and others who need assistance, by denying them the overtime wages they earned. Investigators with the department’s Wage and Hour Division found that Attentive Angels Home Care LLC paid employees straight-time rates when they worked more than 40 hours in a workweek, a violation of the overtime requirements of the Fair Labor Standards Act. The division’s investigation recovered $120,321 in back wages and liquidated damages for the 36 workers.
