What is a common consequence of being overly tired on the job?

Being overly tired on the job can significantly impair a person's ability to perform tasks safely and effectively. When someone is fatigued, their cognitive functions such as attention, alertness, and decision-making abilities are diminished. This results in a higher likelihood of mistakes and oversights, which can lead to accidents in the workplace. Fatigue can affect coordination and reaction times, making it more difficult for individuals to respond appropriately to changing situations or to operate machinery safely. Therefore, the increase in accidents is a direct consequence of the decreased physical and mental capabilities associated with being overly tired. This highlights the importance of rest and managing one's workload to maintain a safe working environment.
