It sounds like you are lucky - you have an employee who feels comfortable being honest with you about his work-related feelings. Why not ask this employee - perhaps in a neutral place like at lunch - what he thinks? I'd ask whether the employee was uncomfortable because he used to have a boss who treated him badly and liked to yell and throw tantrumswhile open carrying (an awful combination for anyone!) or if it was the open-carrying in and of itself, even if the boss had been a great guy.I'd be honest with my employee and tell him that I sometimes open-carry, and I respect my employees feelings a great deal, so I need to know so I can take that into consideration. Most employees would feel valued to have their boss be so considerate of their feelings and curious aboutthe employees previous experience with variousmanagement styles. That could lead to an even better employee who sticks around.
