With your attitude you must have a big turn over in employees.
Firearms in an employee's vehicle to a large degree is about safety to and from work (plus the 2nd Amend).
It is a lousy boss who never thinks employee safety.
First of all, I would never hire anyone who thinks that the 2nd Amendment governs the relationship between private individuals. That is so dumb that I would assume the applicant is a liberal and I don't knowingly hire liberals. Second, I would never hire anyone who thinks they are entitled to a job at my place of business, because I assume that anyone with a sense of entitlement is a liberal. Third, I would never hire anyone who believes they have a superior right to set the rules of behavior on my propery because again, I would assume they are a liberal.
