In other words, the same people who hold weekend lines under PBS will hold relief lines or reserve and still work the weekends. It's not hard to believe, but if you look at relative seniority, the people who hold full weekends off will be at the same %, the people who hold partial weekends will be at the same % and the people who can't get weekends off will be at the same relative %. The end result is not going to be that different, except when the dust settles, you still have better trip trade/drop rules.

Don't mistake the line delivery system for work rules. Your work rules after the lines are delivered are awesome, your line delivery system not so much.
