Wonder if this is related to the Oklahoma case where a paper mill’s employees were fired for having a rifle in their locked pickup.
What used to be a private matter (whether you own a gun, how many guns you own, whether you have CCW) is increasingly becoming publicly discoverable. More companies are doing background checks on prospective employees, and on current employees before promotion. There is an increasing likelihood that your status will appear on such a background check, and will factor into employment decisions.
