It wasn't so many years ago that if you had just merged two global companies, you might communicate the details of this to the staff by sending them all a memo.
Such a memo would no doubt have spoken about "opportunities", "synergies", "securing the future", and that kind of corporate guff.
Arcelor-Mittal does it with a dedicated TV series, which employees can view on-line, to get the inside story of the merger and what it means for their job. Nice, I like it. (This via Real Business blog).
I have a similar plan (albeit on a slightly smaller scale): in our new office (which we should be occupying in April) we are going to have a webcam permanently broadcasting what's going on in the office, so you can all see how hard we work juggling the day around to get our handyman to your door on time.
