ARTICLE 15 REDUCTION IN FORCE
(a) All demotions and reductions in force of full-time and part-time employees for lack of work will be handled separately in accordance with Occupational seniority, as provided for in Article 10 paragraph (f).
(b ) An employee who has completed his probationary period and is directly affected by a reduction in force may, at his option, select one of the following:
Option A Accept layoff. Severance would be provided under Article 37 and the employee would retain recall rights per Article 16.
Option B Request to exercise seniority at his station or in the system.
(1) Local Option:
Exercise his seniority to fill a vacancy or displace the most junior employee at his station in his own or lower classification within his Title Group, full or part time, or
(2) System Vacancy Option:
If he has six (6) months or more of seniority, he may exercise his seniority to fill a vacancy at another station in his classification in either a full-time or part-time position, excluding Higher Capacity positions, in which event he will have preference over employees who otherwise might qualify under the provisions of Article 12(l) or 12(m), or
(3) System Displacement Option:
If he has two (2) or more years of seniority, he may exercise his seniority to displace an employee, as outlined in paragraph (c) with the least system seniority in his own classification or any lower classification, in either a full-time or part-time position, in which he has successfully passed or can pass the appropriate qualification test.
(4) Retained Seniority Option:
If an employee is retaining seniority in another Title Group, he may exercise retained seniority in any former or lower classification at his current station. If that Title Group does not exist at the station where the reduction in force occurs, then the employee may request a transfer to any existing vacancy in the system within the Title Group in either a full-time or part-time position. An employee exercising this option will have preference over employees who otherwise qualify under the provisions of Article 12(l) or 12(m). If there are no vacancies as referred to above, then he may exercise his retained seniority to displace the employee with the least system seniority in any former or lower classification within the Title Group, in either a full-time or part-time position.
