Shift Bidding and Transfers. (i) Shift bidding is the selection of a new shift schedule within the employee’s general classification or special assignment. Shift bidding may occur once annually during the fiscal year between November 1 and November 15. Annual shift bids will take effect between January 1 and January 7 of each year. Shift bids may occur more often if triggered by a vacancy created within one of the general classification schedules when an employee is promoted to a higher rank, transfers to a different general classification, retires or terminates employment. Shift bids created by vacancies, promotions, etc. will take effect as soon as practical.
