Note to occupational health. When you do the sight test for someone who has achieved promotion to driver, let them wear their glasses. After all, they are hardly going to get in the cab and take their specs off, are they?!
Rumour has it that a CSA, having passed all the tests for driver, may have been knocked back after passing the sight test with glasses on but failing it with them off. Tubeworker can not believe that management would cause such an obvious injustice through such a basic mistake.
