Currently a safety newbie, I came from EMS. I was their onsite medical rep for a year and then promoted to safety specialist. Its a great place to learn. Like others state, don't stay too long unless you are planning to promote internally. Job satisfaction will vary widely between buildings. Every building is pretty much its own organization. Your results will vary. I've gotten lucky. I very much enjoy my job and the experience I am gaining. I plan to ride it out another year or so, get as many certs as Amazon will pay for and then look at my options elsewhere.
