It doesn’t happen too often in a “normal” working environment unless you work in a matrix structure where project teams are often different. During my time in the army it happened a number of times. And I remember quite vividly when during officer training our team of 8 got mixed together and over a period of 3 days we had to work our way back to base camp with different leaders and challenging tasks on the way. A number of times we were not united and had strong words with each other. Some coped better than others when they were in the leadership role.
