Rules, procedures, and supervision in the workplace are important, but they should only exist in moderation. In a lot of workplaces, there has been a shift away from rigid structure toward flexible working hours and more flexible rules.
For example, having a rule that everyone needs to be at their desks and working by 9 a.m. at the start of a workday means maximizing the output that your company can achieve that day. However, if you berate somebody for being late and only being at their desk at 9:02, you will create a culture of demoralization, which is counterproductive.
A fine line must be drawn between supervision and micromanagement. While supervision is a great way to make sure that everyone is working to the best of their ability, micromanagement (looking over someone's shoulder and monitoring their every move) will cause them to be irritated and despondent.
