“I don’t know, Jess,” he said to me. “It just seemed like the thing to do at the time, but now that I look at it from here, I don’t know what the heck I was seeing and thinking. I would normally never attempt anything like that. What’s wrong with me?”
I could see genuine wonder and concern in his eyes, so I asked, “How many hours have you worked over the past two weeks?”
His reply answered his own question. “One hundred seventy-eight hours according to my paychecks, and we’ve worked 16 hours per day for the past three days. Jess, you know we’ve just been doing what we have to do to meet the outage and final tie-in deadline.”
And in that brief exchange, we see how fatigue builds and an example of how it can affect you, me and our crews.
