holiday help seasonal workers

“If you have at least 50 full-time employees, including full-time equivalent employees, on average during the prior year, your organization is an ALE…. If your workforce exceeds 50 full-time employees for 120 days or fewer during a calendar year, and the employees in excess of 50 during that period were seasonal workers, your organization is not considered an ALE. For this purpose, a seasonal worker is an employee who performs labor or services on a seasonal basis.”
