Best Answer Thanks! Most states define part-time employees as those who work less than 35 hours per week, compared to full-time employees who typically work for 40 hours or more. In California, the Department of Labor Relations states that a full time employee is someone who works 40 hours per week or more. Many companies offer their own definitions of full time and part time, and it can be confusing to know for sure whether you are legally eligible for full time benefits or not.
