The Mayor may, whenever he or she deems it to be appropriate and in the public interest, authorize one or all of the following:
Each employee shall be responsible for reporting for duty at the late arrival time, even upon the occurrence of conditions beyond the control of an employee, such as inclement or hazardous weather or a transportation disruption.
Whenever the Mayor determines that a late arrival policy is in effect in accordance with Subsection 1273.1(a) of this section, an employee, other than an essential or emergency employee subject to the provisions of Section 1271 of this chapter, shall be authorized to arrive late, up to the number of hours specified by the Mayor, without loss of pay. An employee who utilizes leave for the entire day when a late arrival policy is in effect shall be charged the appropriate leave for the entire day.
Whenever the Mayor determines that an unscheduled leave policy is in effect due to a declared emergency in accordance with Subsection 1273.1(b), an employee, other than an essential or emergency employee subject to the provisions of Section 1271, shall be permitted to utilize annual leave, compensatory time, exempt time off, or leave without pay, for all or part of that day, up to a maximum of eight (8) hours or the number of hours worked under an alternative or compressed work schedule, if applicable, without obtaining advance approval or providing detailed justification. The use of unscheduled sick leave must be approved in accordance with Section 1244.
Whenever the Mayor determines that an unscheduled telework policy is in effect in accordance with Subsection 1273.1(c) of this section, an employee on a telework agreement may telework. An employee must inform his or her supervisor and timekeeper (or equivalent) of any unscheduled telework day(s) taken pursuant to this section.
Whenever the Mayor determines that an unscheduled telework policy is in effect, an employee designated as an emergency employee who is activated is required to report to work unless he or she is directed to telework.
An employee who does not report to work (or who does not telework, when authorized to do so) and does not request leave during a period when an unscheduled leave or unscheduled telework policy is in effect, and refuses to consent to any type of leave upon return to duty, shall be charged with absence without official leave.
