Here's another job title which tends to be met with a derogatory response. The impression people have of health inspectors or safety executives is that they're only in their position to spoil everyone else's fun, or place unnecessary restrictions on working practices. They're the reason you might be asked to wear goggles at work for tasks which clearly don't require them, or conduct a risk assessment in writing before ordering new chairs for the office.
The role does have a function though - it's to protect whichever company they're working for from lawsuits, and diminish the risk to human health and life. A degree in the field you're working within will be required, as will formal certification and up-to-date knowledge of health and safety law, which changes regularly. Investigating accidents also falls under the purview of these roles. It's a lot of responsibility - and so it pays a lot of money.
