Reasonable duty cycle of shifters

By-Laws
E.3 Shift Scheduling and Shift Counting
   1. The collaboration Shift Scheduler will revise the membership list of the collaboration maintained by the Collaboration Board (CB) at each collaboration meeting.
   2. Shifts will be assigned in blocks to all member institutions in proportion to their number of members. A shift-trading period will be organized by the Shift Scheduler to allow foreign, domestic, and local institutions to optimize their periods of shift-taking responsibility to their needs.
   3. Each member of GlueX is expected to take shifts. The minimum number of shifts required per year is one half the average number of shifts per person that need to be covered by the Collaboration. [Example: during a 240-day year of running, there are 1440 shifts. If the collaboration has 120 members, the minimum number per person is (1440/120)*.5 = 6.0 → 6 shifts]. Training shifts do not count as shifts and are the responsibility of the individual/institution to qualify to take shifts.
   4. The activity of the RC "counts" toward the shift responsibilities for the RC's institution at the rate of one shift per day.
   5. If a shift goes unfilled, either by no-show or no-qualify, the incident will be brought to the attention of the Collaboration Board for possible action.
   6. Under exceptional circumstances, the shift scheduling and shift counting for an institution will be revised by Hall D Collaboration Executive Group.

Proposed change:

1. For any individual collaborator there can be no less than 12 hours between the end of one shift and the beginning of the next. Exemptions may be granted by the PDL.

Features of this rule:

Rules out back-to-back shifts.
Allows one to do, for example, a noon-8pm shift followed by an 8am-4pm shift the next day without an exemption.
Allows some flexibility via the PDL-granted exemption.
