You must turn in a Request for Medical Care form (sick slip) to be seen during sick call. If you fail to turn in a sick slip or miss a sick call for any reason you must wait until the next scheduled sick call. The nurse is here on a regularly scheduled basis and will see any inmate who fills out a Request form.

Sick slips are distributed by the Housing Officers. The inmate completes the form and returns it to the Housing Officer. Inmates are not allowed to accumulate sick slips to be used later. Sick call is conducted by Licensed Medical Personnel.

If you become ill, you should notify the Housing Officer in order to receive prompt medical attention. Inmates are required to pay for some medical services. Other services are free of charge to the inmate.

Medical care is never refused for inmates who do not have money in their Commissary Account. However, the account goes into a negative balance and if money is received into the account, it is deducted.

Inmate Worker

Certain inmates are selected periodically to serve as Inmate Workers in the jail and to work around the jail without pay. Selection of an Inmate Worker is made by the Shift Supervisor. Inmates eligible for consideration as an Inmate Worker are those who are considered to be a good security risk, and who show promise of good behavior and consistent work habits. Inmate workers may be sentenced to the County Jail for a period of 364 days or less. Inmates with Hold Orders will not be considered. The selection to be an Inmate Worker is a trust, not a right. You may be terminated as an Inmate Worker at any time for any reason. Any inmate who refuses to work will face disciplinary action, loss of privileges and/or including loss of good time.

Law Library

Inmates may request to use the available Law books in the jail by asking a Housing Officer. Housing Officers supply the law books to the inmate as they become available.
