I don't think there is any penalty for rescheduling shops on the iSS platform. If the shop is not allowed to be rescheduled - the reschedule button won't appear. I was recently awarded 165 shops from one MSC. We set it up that I would do a route each Thursday. However, we only did that to get the shops assigned to me. Each week I move the dates around so that the shops fit in with my other shops. Basically, I'll be rescheduling 165 shops. If there was a penalty I would have been deactivated by now, right? We do this quarterly.
