Your old facility's MOU in not in compliance with the CBA. My old facility was handling it the same. Facrep insisted it was permitted. I disagreed, and so did the RVP. Then it got fixed.
Two consecutive or non-consecutive weeks including RDOs means any two seven consecutive calenday day periods OR any single period of 14 consecutive days (7 days + 7 days).
When either of those periods start is at the discretion of the employee.
Example: Any employee, regardless of crew assignment, would be allowed to bid from August 1 through August 14.
That same employee could also bid from August 10 through the 16 and from Nov 20 through Nov 26. Doesn't matter where his/her RDOs fall.
All seven-day periods would be protected from OT assignment...
