I will never forget the time, many years ago, when an employer insisted that everyone in the company take a "leadership test" designed to show the management and leadership potential of each employee. I made it clear from the beginning that I considered the whole thing to be bogus and a rip-off. I was informed by my boss that it was indeed mandatory and that I was rightly scared of the test because he felt it would show that I was, as he had previously told me, that I was not management material.
So, I went along and took the test, which included an assessment of each employee by all the other employees.
Three weeks later we were all herded into a conference room for the unveiling of the results. The coordinator of the test preceded the unveiling with a fifteen to twenty minute explanation of the chart we were about to see. Guess what? When the chart was revealed, I was the only one of ten employees that hit the mark exactly as the perfect manger and the manager was the only one who tested as having no leadership qualities; even the porter rated higher in management potential and he was a high school dropout!
So much for personality testing! Toss them in file thirteen where they belong!
