You are working alone and your shift is due to be over at 6 pm the individual who is scheduled to begin working at 6 pm does not show up .what do you do?

contact your boss, explain the situation, you ask to be releaved or get paid double time for overtime, if that is not an option close up shop, and make sure everything is secure and locked up properly, then go home. You have done everything you are supposed to do, now the resposibility rests with your boss.
