Paid sick days are important for workers and their families. Nearly 40 million US workers do not have paid sick time. When sick children cannot stay home because parents lack paid time off, children may be sent to school sick. Losing pay from taking unpaid time off can seriously hurt family budgets. While providing paid sick time costs employers a small percentage of total sales, the benefits to employers include reduced turnover and increased worker loyalty and productivity. A case study in Connecticut found the costs to employers to be very low compared to the benefits.
