For purposes of this section, the term "detail" means the temporary assignment of an employee, without change in a pay category, to one of the following:
During a period of detail, an employee shall remain assigned to the official job, and the employee's rights and pay shall be based on the official assignment, not on the duties or job to which he or she is detailed.
Employees may be detailed on an informal basis for up to thirty (30) days, or officially detailed for periods in excess of thirty (30) days but not more than one hundred twenty (120) days.
Details may be made based on semester breaks, if appropriate.
The Director of Personnel shall be authorized to extend details beyond one hundred twenty (120) days.
The terms of any negotiated collective bargaining agreement shall, as to details, supersede this section.
