If you are done, and the green light of death comes on, do not touch your board until you get back to the building. When you get to the building, message back, "I am at the building, do you want me to go back out." Then sit and wait for an answer. NEVER use your phone if they are forcing you to help. Tell them to set up the meet.
If you are on the 9/5 list, reply to every 'can you help' message with, 'am I being forced.' Wait for an answer. If they are telling you to help with the 1st message, reply with, "what is the meet point.' If they do not reply with a time, ask for that, do not move until you get a reply.
You have to work as directed, but make it as painful as possible.
