It would be safe to guess that the number one reason people leave their job is lack of compensation. But your guess would be wrong.
I have served as an administrative assistant. Often time I felt overwhelmed with tasks and responsibilities. However, to keep me going, all it took was a little encouragement from my boss and coworkers acknowledging that they saw the work I was doing and appreciated my commitment. This simple action fueled me and gave me the motivation to keep doing my best every day.
