This is bad advice. Business is business no matter how many times you claim your team is like "family" or "friends". One place I worked at was very friendly and supportive. One day the founders, who are still my friends and mentors, faced an extremely lucrative acquisition offer that resulted in firing half of the team, myself included. They announced and completed the whole transaction in a matter of days, and I don't blame them - if they announced too early, people would have fled or leaked the negotiations, failing the deal of their lives. So when time comes, even the friendliest management will not give you any warnings, why should you? There is nothing to gain.
