An activity is an event or a recorded historical occurrence of something that transpired against the members record while they were a candidate on the out of work list. It can include: dispatching, attempted phone calls, voice messages that were left on the member's phone, rejecting a job, etc. There are numerous things that can classify as an activity and in fact, the organization gets to decide what makes up its own collection of activities. An activity rule is a rule that is applied on the basis of some sequence of activities. These rules might include: moving a member to the bottom of the list when they reject a job opening 3 times inside of a 2 month period, or pulling them off of the list entirely if they have worked a short term job more than 11 consecutive days. There are literally thousands of possible 'rules' that can be created.
