I’ve worked for UPS for the last three years and recently I accidentally brought in a firearm without realizing it. I’m unsure how the security personnels didn’t see when I put my bag through the X-ray belt. I realized I had it on me during break time when I reached into my bag and I felt it. I immediately went to tell the security personnels and they called some other people from in the hub I had to speak to speak to, including a union steward. I was terminated as they took my Id and sent me on my way. Is there any possible way of appealing since I didn’t know I had it on and the security personnels didn’t see it on my way in?
