Thirty years ago, many people actually retired from the same company they began their career with. A health and safety career was often marked by long tenures with one or possibly two employers in the same community. Stability made it rather easy to chronicle a history of health and safety activity in these companies; past programs, incidents and controversies could be culled from the memories and experience of just a few people, or they were amply recorded in paper files.
Today, any ties that bind have been largely severed. How many people have held your health and safety job before you? Where have they gone? How long before you move on?
