Alternative Work Schedules

An alternative work schedule consists of two components:   flexible bands and core hours. When working an alternative work schedule, an employee must be on duty during core hours.  The flexible time bands are the times during which employees may vary their workday starting and ending times as follows:

Core Hours and Flexile Time Bands

Band/Core Hours Begins Ends
Flexible Band 7:00 a.m. 9:30 a.m.
Core Hours 9:30 a.m. 11:30 a.m.
Flexible Band 11:30 a.m. 1:30 p.m.
Core Hours 1:30 p.m. 3:30 p.m.
Flexible Band 3:30 p.m. 7:00 p.m.
