speaking generally, I don't think of businesses that way. If my hypothetical friend was fired without cause, say, and the person who made the decision had a real stake in the business I did with the company--meaning my doing business with them actually benefited that person--then I would probably not shop there or whatever.

In contrast, if some company president made a business decision to cut staff, including my friend, I don't see why I should try to punish that. I just don't see the point.
