Question, Got shot in the back during first day working Katrina, and employer wonders why I won't go work Isaac.

Question at the bottom. I am a lineman for a power company, and my employer is pissed because I decided to take some time off to get a abdominal hernia fixed, since they wanted us to go to New Orleans. I feel bad that my crew is heading there now, but I told them I would never again work a storm in New Orleans ever again. I have never worked a area and been scared for my life before. August 30th 2005 was our first day out there. And had to run from gunfire twice. The second time a 9mm bullet hit me in the back. Thankfully it was near my shoulder and did not hit anything major. It was a group of people screaming "kill those white cracker bitches". I have been working with this hernia for a while now anyways. And I am feeling really guilty about leaving my crew. But they wanted the overtime. Lots of crews have worked down there, I was just in the wrong place at the wrong time. But a few lineman were killed down there in 2005.

Is it wrong for me not to go?
