I likewise have decided to "drop out of the loop" with this rule. OPSEC/COMSEC is the reason they give, but at the same time there has to be a way to have some kind of non-secure commercial email access. My Guard unit has always been great about paying you for the days your work, but if I had a situation like alluded to above where an ART implied you should work a full day for a 4 hour pay period then I would completely ditch checking email at home. We don't solve budget issues by taking it out of the hide of the guys who are still trying to serve the team...
