If you share ownership with one or more partners in your company, then at some point there may be a need or desire to buy out that person. This transaction can go well, or not well.
If it goes well, a buy-out of the right person at the right time and in the right way can propel the business forward with new vigor and clarity. If it goes not well, bad things can happen to employee morale, customer relations, and the bottom line. Sometimes buy-outs happen on a planned basis, and sometimes life throws a curve ball and a crisis occurs.
