(l)(a) When permanent vacancies occur on a regular must fill job, (conductor/foreman and first brakeman/helper positions) , Guaranteed Extra Board position or Reserve Board, employees may elect, by seniority option, to fill the vacancy. If the vacancy is not filled, it will be filled by the recall of a furloughed employee. If the vacancy is filled, the resulting vacancy will be processed immediately following the above-described procedure. This process will continue until a furloughed employee is recalled. If no furloughed employee is available, the junior employee among those holding second brakeman/helper positions and the Reserve Board at that Reserve Board location will be assigned. If no such employee is available, the junior employee for that prior rights territory among those holding second brakeman/helper positions or the remaining Reserve Board will be assigned. The application process, rather than bulletins, shall be used to fill these vacancies.

(b) Employees recalled from the Reserve Board shall have the right to exercise their seniority and take any position held by an employee with less seniority.

(c) No temporary vacancies on any blankable second brakeman/second helper position to which an employee is regularly assigned shall be filled.

The "Sadie Hawkins Day" shall operate only for employees wishing to exercise seniority to or from a Reserve Board. Local Chairmen will work with Carrier representatives in the implementation of "Sadie Hawkins Day." It is understood that an employee on one Reserve Board may not place on another Reserve Board, unless displaced.
