Some employment positions on campus, while considered full-time, are not twelve-month positions. These employees do not receive a paycheck during the months they do not work (usually summer months); therefore, their ID cards will be deactivated until they return to work. Because these employees are by policy covered by benefits yet have no earnings from which to withhold benefit contributions, they would have a larger amount withheld from their pay during the months they work in order to cover insurance contributions, especially for those having their benefit contribution withheld on a pre-tax basis.
