How professional get the work done

Professionals can get their work done without using emotion to signify urgency.

When a surgeon asks the nurse for a scalpel; she doesn't have to raise her voice, stamp her foot, nor even make a face... She merely asks.
When a pilot hits a tough spot, he's not supposed to start yelling at air traffic control. He describes the situation and gets the help he needs.
And despite what you may have seen in the movies, successful stock traders don't have to start screaming when there's more money on the line.

Compare this to the amateur world of media (even social media), of customer service, and of marketing. Whoever yells the loudest gets our attention.

May it be Facebook users who use cutting language and ALL CAPS to get someone at a company to feel bad; or those emailers (who should know better) who mark their notes as urgent, even when they're not.

It should be clear (compared to say, surgeons and astronauts) that these people aren't angry because so much is at stake. They're angry because it works.

The problem with requiring people to be loud and angry to get things done is that you're now surrounded by people who are loud and angry.

What happens if you take a professional approach with the people you work with?
What happens if you prioritize those who properly prioritize their requests and ignore those that seek to escalate via unnecessary escalation?
What happens if you consistently enforce a rule against tantrums?

If you consistently reward professional exchanges and refuse to take action because it's raining with pointless anger, the people you work with will get the message.

A pitfall of throwing tantrums is that sometimes, people throw them back.
