Section 1. (a) When permanent vacancies occur on a regular must fill job, (conductor/foreman and first brake-man/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 will be assigned to the regular job or guaranteed extra board; however, they will not be forced assigned to the reserve board. If no such employee is available, the junior employee among those holding Reserve Board positions will be assigned. The application process, rather than bulletins, shall be used to fill these vacancies. If the vacancy cannot be filled in this manner, existing schedule rules will apply. (See Side Letter #6, Paragraph 2 and Side Letter #20)

(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. (See Q&A #2)

Section 2. For eligible employees on the First Seniority District, there shall be a so-called "Sadie Hawkins Week", the first week of May to be effective June 1, and the first week of November to be effective December 1. The "Sadie Hawkins Week" shall operate only for employees wishing to exercise seniority to or from the Reserve Board. Local Chairmen will work with Carrier representatives in the implementation of "Sadie Hawkins Week".
