You are not allowed to bring weapons into the building. You may or may not get a warning before being fired.
Can you imagine how your peers will feel? How they will think you are going to go on a rampage? If you can’t feel safe at work without a gun you either need therapy or a different job.
Having a CCW permit is an enormous responsibility. So much as pulling out and showing a firearm, even if it's not discharged will get you into the biggest legal fight of your life. Likely it will be confiscated. You will amass huge legal bills. There is absolutely no need on this planet to pack iron while working at Target. You WILL be caught, someone will see it and report you. Get help. You need it. Please.
Jesus use some common sense. You asked if you can work with a gun and the answer is no. You may not. You aren’t a guest when you get paid to be there. If you’re this obtuse in real life no wonder you don’t feel safe at work.
