In every job, regardless of position or title, there are people who are effective at the job. And there are people who may be qualified for the job, but not terribly effective.
Being qualified for the job doesn’t automatically guarantee that you’re going to be effective at it. You may have seniority, or your certification, or a love of safety. These don't guarantee that you'll be effective at the job.
The job of a safety person isn’t to be a hero or to save people’s lives. The biggest part of the job really is communication. Safety people and supervisors are supposed to influence, coach and mentor employees to make good decisions.
To become much more effective and make a bigger difference, understand that your people don’t need your protection. They need your guidance.
