¹  Flexible workschedules refer to a variety of scheduling arrangements in which fixed times of arrival and departure are replaced by a workday or workweek composed of two different types of time--core time and flexible time. Core time is the designated periods during which all employees must be present. Flexible time is designated as part of the schedule of working hours within which employees may choose their time of arrival and departure from the office, within limits consistent with the duties and requirements of their position.

² Compressed work schedules, which may take a variety of forms, require full-time employees to work 80 hours in less than 10 days in a pay period. Also, the times of arrival at and departure from the office are regular and fixed under a compressed schedule.

³ Of the 2,230 collective bargaining agreements in the LAIRS file on July 1994, 453 contain clauses on flexible and/or compressed work schedules.
