To determine whether you may be working tired, ask yourself the following questions:
Before starting work:
•Did I get less than 6 hr. of sleep last night?
•Have I been building a sleep deficit over time?
•Did my shift require me to wake up extremely early in the morning?
•Am I working a series of shifts that require me to get up at progressively earlier hours?
•Have I been asked to work longer hours than normal?
During the shift:
•Am I slower than usual in performing a task?
•Am I having a tough time finding the right words when communicating with others?
•Did I forget someone telling me to do something?
•Am I generally feeling short-tempered?
If the answer to any of these questions is “yes,” you may be fatigued and therefore more prone to making an error on the job.
