I would be happy to share a success story.
I was almost killed one day at work when 70 000 lbs. of steel came crashing down. I have the full story about my close call at work in my Bio section.
That close call changed my out-look on workplace safety forever, subsequently, I became the certified trainer for our over-head crane.
My training classes always started off with "My Story". This gave the training a new dynamic, it gave me something to get their attention, and hold it. No one fell asleep in my class!
I love training, and miss it very much.
I do have a story that I was told in my class from an instructor, it's a story about the things we do without thinking.
One day a worker looses a quarter of his finger wile working on a machine.
The boss comes in, and can't understand how it happened.
The worker recovers, and returns to work some weeks later.
He is asked by management to demonstrate what had happened to cause his partial amputation.
The worker climbs up to a hole on the machine and Say's "I was lining up this hole with my finger like this and"... Chop!
He lost the rest of the finger by showing how he got hurt.
All you trainers out there, feel free to use this story in your training classes.
