I am in the AF reserves as well but have not broached this subject with my LoCo carrier for fear of the answer. So far my small duty stints have had no impact on my employer. I believe I could take unpaid leave for a short while, let's say up to 60days but anything more than that, I think I would be fired. It is a gamble, I'm just hoping there is no activation in the near future...
