To deal with this situation, Jefferson Lab leadership has developed a new [https://userweb.jlab.org/~kuhn/BONuS12/Documents/shift-policy_20200317.docx POLICY] that requires only an expert shift taker during Day and Swing shifts (Owl shifts will still be covered by 2 people). There will be remote backup ("Ghost Shifts") for some of the worker shifts during Day/Swing - '''please read the instructions under the "Remote Shifts" tab and make sure that Bluejeans is properly connected (Screen share and audio)'''. All counting houses have been equipped with a direct camera feed so that shift takers for ANY hall can monitor the counting houses of Hall B and Hall D when only 1 person is present. Shift Experts will carry a cell phone that can be used to call in help. IF YOU ARE ALONE ON SHIFT, you may not go into the Hall - call the relevant experts instead. Shift experts during Day and Swing are expected, in addition to their regular duties, to also check monitoring histograms and CED and log them (as well as standard screen shots) to the logbook, and to respond to any alarms, as well as fill out shift checklists. These new rules take effect on Tuesday, March 24. |
Starting immediately, please follow these rules: Keep a distance of 6 ft from all other people AT ALL TIMES. In particular, expert and worker (when both present) should sit 6 feet apart, facing in different directions. In addition, only the RC OR an RTPC expert should be inside the counting house B at any time - a maximum room occupancy of THREE has to be obeyed at all times. The RC, PDL and shift expert have the authority to ask non-essential people to leave if overcrowding occurs. Any work that requires 2 people to work in closer proximity than 6' must be first approved. | Starting immediately, please follow these rules: Keep a distance of 6 ft from all other people AT ALL TIMES.
