Mental note: when having a fight with a coworker, NEVER, EVER under any circumstance call the person and leave a message stating you dislike the person. probable outcome will be that the phone is brought in as evidence, the message played to a HR representative, and you will be cited with unprofessional conduct. the result? skip 3 levels of displine, and you find yourself dazed and confused wondering what happened.
better method? have a one on one argument with someone, hash it out. and then its their word against yours. no witnesses (just a little blood if the situation warrants)
is what makes this particularly painful is it happened to one of my best people.
result to business? best person gives 2 week notice.
