Once you stop missing something (field circus, meetings, conventions, etc) they will try to find out why. They couldn't give a rats a** about you while you are in but once you turn up missing, they are on your tail. Darn busy bodies. Play the dead rat. Play dead and the cat will loose interest. Ha!
Don't tell them a damn thing. Stay in control, don't give them power over you. You are in the drivers seat NOT them. Once you start running your mouth....BAM they have you right where they want you.
Use the sick, busy excuse. That's what we have been doing. So far so good!
You're young and the young are leaving in droves. They are getting VERY worried. As they should! They did it to themselves!
