In a cube farm, you typically hear the word manage when the boss comes around. The boss talks about needing to manage projects or employees or whatever else needs managing that day.
In many cases, you only see your boss when you fail to meet expectations, or they know that there is some deadline approaching. This also inspires fear in many employees because your manager only appears when something is wrong.
What if you had a different relationship? What about your peers? Do they know what to expect from you when you work together? All of these things require management. You need to manage your boss, your coworkers and your career.
