@Linkat,
I know this is a late response, but about that time difference...I have a suggestion, but your the best judge of how this would work.
You could draft a memo informing the associates that: due to staff changes (we)or (Boss) we will(stream line) or (reorganize) or (redirect )certain functions/meetings/calls/faxes and we will be making these changes by (pick a date) (Im sure Im not describing the actual functions, but you can just use it as a template and make it yours.
Preferably get her to sign or authorize you to sign
What I'm thinking is if she sees on paper how this change will be made, she may decide the proposed change shouldn't be changed,
Or she will want to sign it as written and then at least you can inform your associates what's happening. and how the change will affect their duties.
If you know or even suspect she would take offense, don't do it.
Its been my experience that each time a new manager takes charge they want to change things to make it theirs.
(This is not my best effort, but it's 4 AM here and I can barely keep my eyes open, So if you see something you like use it, if my language was unclear I can take another stab at it later today, don't bother with any parts of that little blurb that don't work for your situation.)
Ive got to hit the sack
