I have not been "allowed" to carry at work by company policy for the last 40 years by 3 or 4 different companies. With the current mind set of digruntled employees to go in a place of employment and "get even" makes glad I did and still do.

I have carried every day in a professional & managerial or in consulatant environment in some way or means as I will not be anywhere unarmed at anytime.

Get good training such as Thunder Ranch or Gunsite and keep your training up to date.

Concealed means concealed and if you don't talk about it and dress around the weapon no one will ever notice.

Having a good job and obeying some rules doesn't mean squat if you are dead.
