May your code run on the second try. Because if it works the first time, that's suspicious. And if it fails the second time, that's frustrating.

• Happy landings
• Keep the blue side up
• May you have fair weather and clear skies

“Hopefully we’ll see you back here in a bit.” - tacitly acknowledging that, uh, certain jobs and worksites have incredible danger and uncertainty attached to them.

"Don't let your knuckles be whiter than the clouds below you."

I climb communication towers, and let the new guys know not to over grip the tower. Trust in your harness.

Hope your Friday is read-only. Because no one wants to ship code changes on a Friday. (No one will be there on the weekend to babysit changes)

One thing that was common in my EMS organization.

Don't say the 'Q' word!

Q=quiet. If you say 'it's a quiet night, you're sure to get slammed.

Not my line of work, but I think that acting's "break a leg" is a pretty oddball benediction.

Working in maintenance, automation to be specific, and I always leave the site with "I hope I never see you again!" to the client.

May your knife chip and shatter

May you have no teacher dreams. Teacher dreams, common among teachers, generally have you going to class unprepared or having a class out of control.

Back in the Klingon Navy we just said "die with honor".

Not officially, but I've definitely said to coworkers "I hope your meetings are cancelled"

One that I read that I found interesting is in the busking community is "fat hats!". Since they sometimes use a hat to collect donations, it's an expression that you hope they collect a lot of money.

good luck fuckface!

I worked in an ironworks and that's how most shifts greeted each other.

When people are working I like to tell them I hope it goes by quickly. They prob'ly tired.

Woodworker - I'm careful complimenting a piece someone's midway on in the workshop, just in case I accidentally curse them to screw it up in the final moments

Fortunately it's not hard to touch wood just in case

Can't think of one right now, but what it should be is "I hope all your tool batteries don't run empty at the same time"

Not a job (although it takes up more than 20 hours of my week), but we commonly say "Have a good treatment!" as a greeting/goodbye at dialysis (to other patients, of course).

What area of the world do you live in? In my neck of the woods wishing a "boring shift" or a "quiet shift" is considered a curse and will bring about all the crazy cases.

We typically wish each other a "safe shift" instead of a "quiet shift" here.

get slammed, make money

I mean the classic is actors saying "break a leg" - which actors actually take very seriously.

"Hope there are no notes." Audio Post-production before client playbacks.
