It is not just flexible working we need but a move away from the long-hours culture towards an acceptance that it is possible to be equally committed and productive when working part-time. When returning to work, part-time with a deadline to leave at 5pm each day, I soon noticed how unproductive many full-time employees are. If you don't have the discipline of a 5pm cut-off for your day it is easy to let deadlines and productivity drift during the working day, only to stay late to catch up.
I also find it a shocking waste of company resources when employees (nearly always women) leave beacuse they become demotivated when they find out that they are not valued as highly if they work part-time or on flexible terms. Working-practices that demand full-time work and nothing less are simply outdated and will continue to ensure that experienced and talented employees are lost from every company. There is surely a competitive advantage in seeking to retain experience rather than casting it aside in favour of the diminishing pool of young full-time replacements. The demographics of the employment pool are changing rapidly and so must our working practices if our companies are to remain competitive.
