When managers ask subordinates to take on an assignment, it is often a sign of their confidence in an employees’ abilities and reliability. The same goes for when colleagues ask each other for help.

That can cause the quality of an employee’s work to falter or they are forced to work an insane amount of hours just to get caught up on their to-do list.
