When it comes time for reviews, do these things get noted? Because, a good rebuttal, sans any emotional flare, goes a long way, in a personnel file.

Do you take a detached approach, and say, OK, I get that you don't like the OT racking up due to budgetary constraints, could you advise me, with this schedule, how to accommodate your needs? ((and if they can't, just realize, for some reason, management need not bring employees into their own managerial stressors, and that they, in a way, are crossing boundaries with you, in doing so!))
