Due to the Affordable Care Act (ACA) regulation, employees who have separated and are rehired in the same agency may be treated as new employees under the ACA only if the employee has no worked/paid hours for 26 weeks immediately preceding the rehire date. Those who resume employment without the prescribed separation are considered "ongoing employees" under the ACA and their hours worked in the preceding measurement period must be included in determining full-time status for health insurance.
Therefore, separating employees are not able to work in part-time positions with the college until after a 26-week break in service. This applies to all full-time positions (classified staff and faculty).
