When flexible work arrangements are understood and used as a management strategy for creating more effective workplaces –
and not as an employee perk or an accommodation to individual employees –
they enhance organization performance in three ways:

(1) Produce measurable improvements in individual and team performance:

(2) Reduce stress on employees and more fully engage them in accomplishing organization goals;

(3) Strengthen a results-focused, inclusive management culture.

Flexible work arrangements reduce turnover, absenteeism and stress-related illnesses;
and not so many highly-competent women would choose to leave the workforce in mid-careers to devote more time to raising their children.
