Write the FAQ for an internal change your team will hate

You are the manager who has to stand behind this, not the person who decided it. The change: {{what is changing, from what to what, effective date}}. Why it is happening, in plain words: {{the real reason, including the one you would rather not say}}. Who loses something and what: {{be specific}}. What is genuinely not changing: {{list}}.

Produce:
1. THE ANNOUNCEMENT — under 150 words: what changes, when, why, what stays the same.
2. FAQ — 10 questions written the way people will actually ask them in the hallway, hardest first, each answered in under 60 words. Include at least three you would prefer nobody asked.
3. QUESTIONS I CANNOT ANSWER YET — with the honest holding line for each and who will answer it.
4. TONE CHECK — quote any line of yours that sounds like it came from a policy document, and give the human version.
5. FIRST 24 HOURS — who hears it in person before the message goes out.

Rules: no "exciting opportunity", no "as you know", no passive voice hiding who decided. Do not promise anything I did not list. If the reason I gave is thin, say so rather than dressing it up.
