Thank you, apply flexible policies is a good idea and this motivate employee very well.
Like the resting day, if employee is working and there is no a day to rest, the employee will leave the work.
Because he or she can not kill himself, how can a person will be working without rest, the person will dead quickly, so in case we see such organization have low employee.
The day to reduce working hours, this will make the employee have sometime to rest little before the next day for example, I have someone who there company are like this, which is very Saturday he resume work by 9am and close by 4pm.
This make him more active at work because he knows he will rest on Time when he come back by 4pm.
Activities outside the company,this give more experience to employee and give room for the employee to know more, learn more.
So employee do happy with such organization and such company do have a lot of employee.
