Definite difference between a manager and a leader.

Leaders don't call you at 9:24 in the morning when you're on your way to work to tell you you're late to a shift you're positive doesn't start until 10:30 A.M. Managers do, and they also switch your schedule first thing in the morning when you just checked it at 12 midnight earlier that day to make sure your shift said '10:30 - 17:00 - BACKLANDS.'

Thank you, Managers. Without you, there would be no stress in the world.
