I am the other Guard guy that works with Tommy Knocker. I worked for the company a total of 3 years. 2 the first round (I left due to a slow winter and starting a family needed a steady pay check) went to the federal technician program. But came back over a year ago I love hvac. With that said if this is what you want to pursue hang in there and save want ya can when your crazy busy. I should have listened to the other techs when I left because I would have been a lot further ahead then I am now. As for as being a m-day guard and civilian employment it is highly illegal for the civilian job to not honor your military obligation therefor they cannot terminate you for missing work for military duty. Good luck.
