Reps generally only take meetings off, unless they are volunteers as well. Volunteers get days off depending on the need. Certain groups CNC, PWG, and pairing construction know what days off they are going to need ahead of time and they use IPBs to block off those days. Other volunteers take FPL as needed and as directed by the chairmen of their committee.

Most volunteer come in on their days off and don't get paid for it.
