The Senate health bill requires employers to provide coverage for full-time employees or pay a penalty based on the number of full-time employees in the firm. The bill defines full-time employees as those working more than 30 hours per week. This data brief examines industries with a high percentage of employees who work fewer than 30 hours or whose hours are slightly above that amount, which may place them at risk for reduced hours by an employer wishing to avoid penalties. The industries with the highest percentage of part-time workers or workers at risk of reduced hours are Restaurants, Building Services, and Retail Trade. The industries with the greatest number of part-time workers are Services, Healthcare, and Retail Trade.
