S Contracts and Grad Non-Contract Pay forms for New Hire/Rehire Processing Tip
S Contracts and Grad Non Contract Pay forms cannot be processed for New Hire/Rehire employees until after the effective date on the JED form. For example, a New Hire JED form is processed for John Doe. An S Contract or GNCP cannot be generated until after the employee appears in the system. The effective date is 11/1/02 on the JED. The S Contract or GNCP contract begin date must be 11/1/02 or after.
Therefore, you should hire/rehire Supplemental and Grad Student Labor employees at least one pay cycle before you want to start paying them.
