Our work weeks run Monday thru Sunday, but the 34 hour break in the last 9 days was the only consideration. While pushing the other ceilings (16 in 24, 26 in 48, etc.) is mildly fatiguing, rolling off a month of nights in 24 hours is walking death. Coming out of our last outage, one Tech pushed back on the 24-hour transition. The Company relented after the Union got involved, but only because of how our Contract handles schedule changes: it was cheaper to pay him 10 straight time to stay home than 12 hours double-time to come in. Thanks for your responses.
