We seem to be backing off of the whole "personal responsibility" thing. If you start off with the policy that "we trust all of our employees to behave like mature adults" and they don't, they've demonstrated that you can't trust them, no?

If you have that policy and then start down the road of first-offense warnings, or trying to match the punishment to the crime, you end up in exactly the place where a lot of companies are now. (This isn't a new idea; it's how companies have always operated.) Without a specific set of policies, the company literally cannot do anything right: If you fire someone because his coworkers say they cannot work with him, everyone starts frothing at the mouth. If you pay someone else to leave because he's too important to fire, everyone digs out their pitchforks and torches. If you do nothing, it blows up in your face, spectacularly.

Firing everyone who has any sort of policy infraction fails to note their humanity, and fails to account for the money the company has invested in them.
