Alternate and Flexible Staffing Reference Manual

Job classifications fall in two categories: 1) flexibly staffed or 2) not flexibly staffed (standalone classifications). We describe flexible staffing as a "pattern" of staffing. Flexible staffing refers to the relationship that exists between a group of related classifications in regard to skill level, e.g., Trainee vs. Journey Level. A flexibly staffed classification pattern allows qualifying individuals to promote upwards when the required level of knowledge, skills and abilities has been reached.

A salary differential allowance shall be paid to employees in positions requiring bilingual proficiency as designated by their respective Department Heads or their designee. Said differential shall be prorated for employees working less than full-time or who are in unpaid leave of absence for a portion of any given pay period.
