Catastrophic Sick Leave

The UT Southwestern Catastrophic Sick Leave (CSL) pool can provide additional sick leave if you have exhausted vacation leave, sick leave, and compensatory time accruals because of a catastrophic illness or injury.

A catastrophic illness or injury is defined as a severe condition or combination of conditions that threaten your life or that of an immediate family member, requires the services of a licensed practitioner for a prolonged period, and requires you to exhaust accrued leave and lose compensation from the state.


You work at least 20 hours per week for a period of at least four and one-half (4½) months (unless your position requires student status).

How to Apply

Two forms are required for CSL application:

  1. Catastrophic Sick Leave Request Form (link requires VPN). You (or your supervisor on your behalf) must complete the form and fax to Leave Administration.
  2. Attending Physician Medical Certification (link requires VPN). Your treating physician should complete this form and fax directly to Leave Administration. Your department should never receive/retain this information. 

Once Leave Administration receives the required information, a designation will be made within ten (10) business days. Submission of the application does not guarantee approval. If Catastrophic Sick Leave is approved, you may request an extension if the initial award is less than the maximum.

How to Contribute to the Pool

If you want to contribute sick leave to the pool, submit a Catastrophic Sick Leave Pool Transfer Form to Leave Administration. Contributions to the pool must be in units of eight (8) hours. Sick leave contributed to the pool may not be designated for the use of a particular person and cannot be returned to the contributing employee’s account.
