Management revising duty statement

Hi,

There's been a reorg initiative at my Department where management plans to revise our duty statements to reassign or add tasks that weren't originally on there when hired due to staffing shortages and lost positions. They plan to give us 30 days notice. A few questions:

  1. Is this something we can reject?

  2. Does this open up the opportunity to negotiate with CalHR for a raise if tasks are added? Or will it likely be spinned as just reallocating your existing workload/time? I have concerns they are giving higher workload.

  3. Anyone else experience this before?

Thanks!
