Section 3. In the selection of primetime vacation, bargaining unit seniority shall prevail within the nursing unit and on the shift. Shifts are defined as day, evening, and night. Shifts will be determined by the majority of hours on one (1) of these shifts. However, if an employee works an equal number of hours on two (2) shifts, the employee's shift will be the starting shift. Primetime vacation is designated as June 15 through September 15. No employee may take more than one week vacation (consecutively or otherwise) during the primetime. If no other employee (on the same unit and shift) desires to take the time in question, two (2) weeks’ vacation may be taken, consecutively or otherwise. However, two (2) employees may be eligible to be granted identical weeks off if staffing permits. The Employer shall post a prime-time vacation selection sheet no later than March 1 of each year, and employees within each unit and on each shift shall have the right to indicate their first three preferences in order of preference for primetime vacations. The list will be taken down by March 31 of each year, and a final vacation schedule will be posted by the Hospital by April 30. Employees, who do not sign the prime-time vacation selection sheet by March 31, must submit, in writing, their request for primetime vacation. These requests shall be handled on a first-come, first-serve basis, and the Employer shall respond to these requests in writing. Employees requesting single or multiple days (less than a week) off shall not be arbitrarily or capriciously denied the time off. All vacation requests, including requests for primetime, non-primetime, and holiday vacations are subject to the approval of Nursing Management.
