Delivering bad news about layoffs by any other means than face to face speech can be dangerous. I was an inspirational speaker for a franchise event where I learned that the CEO had laid people off via email only a week earlier. The crowd was still boiling with anger - and it was obvious. News, both good and bad, travels fast these days and information leaked over the Internet only increases gossip and causes fear to fester, further depleting morale and destroying trust.
In any interaction, people need to know what you want. Most conversation involves some kind of objective - there are very few neutral interactions - and the thrust of the interaction is typically understood by those involved, even though it is not stated.
