Administration Teaching. Administrators may teach up to one full course annually provided such activity does not result in a reduction of work for any regular Employee. They may act as teachers on call (TOCs) in case of emergency for no more than one day in any week when a TOC is available. If no TOC is available, the period of acting as a TOC will be extended while the emergency exists. In this subsection, an “emergency” is defined to be the absence of a teacher available to instruct the class.
