Herbert Kornfield, is that you?
Indeed. One of the other doctors heard someone do this and did a bit of a surprised double-take; it was pretty funny to watch.
I forgot, for years we had one woman who worked at the front desk of the clinic, and everyone called her just by her last name. No idea why.
One thing I hate is what I’ve heard from some other doctors’ offices, the practice of referring second-hand to a doctor as just “Doctor.” As in, “Doctor isn’t in” or “Doctor will be able to call you back this afternoon.” Not “the doctor” or “Doctor So-and-So.” WTH.
Large insurance company, first names all the way up. I’ve only met up as high as my boss’s boss’s boss, but it’s always been first names. Even our CEO when he visited (I wasn’t here for that, though). Occasionally will add the last name to clarify, we have a lot of Mikes and Debs.
First names, from the president on down, with a few exceptions:
– The security officers, we are more likely to call Officer Last Name.
– We have one gentleman who is lovely, and looks like a stock character from a movie about Harvard in the 1920s. He’s very tweedy and wears Coke bottle classes. Everyone, again - from the president on down, calls him “Dr. Lastname.” Every once in a while, he asks, perplexed, why no one calls him Firstname. It’s hard to explain, but “Dr. Lastname” is like an affectionate nickname for him because he looks so much like a cartoon character professor. (And he’s not as old as I’m making him sound – he just acts like an endearing old person. From a movie.)
I’m ashamed to admit it took me a minute to get the reference. Came to me before I had to Google it, though, so I’ll have no regrets on my deathbed.
First names. Because of NCIS, I often call my boss “Boss.”
I call everyone by their first name, regardless of position. Subordinate staff call me “Dr. Lastname,” but in Panama staff tends to be pretty deferential. (I’ve encouraged people to call me by my first name, but it hardly ever works, so I just go with the flow.) Students call me by my first name, at least if they know me.
A lot of my employees call me Boss, since I’ve made it clear that uttering my first name is a sure way to ensure a low score on their next evaluation. 
We generally use first manes for people in our group (10 of us); people in other areas are pretty much equally likely to be referred to by first name only, last name only, or first and last name, generally depending on how common their given name is.
So Reinhardt Smith is referred to as ‘Reninardt’, John McGillicuty is called ‘McGillicuty’, and John Smith is ‘John Smith’.
We use first names for everyone from the CEO down. My company has about 30,000 people in it.
Ha !
As an Anglophone I learned that lesson from a Francophone woman in her 50’s while conversing in French in the workplace. When she started after a couple of weeks I was still using “vous”. She basically told me I’m not an old bag you can start “tutoyons” me now.
Currently, it’s all by first name basis. No nicknames, although a colleague started calling me one that I didn’t find very enduring or funny. And asked him to cut it out, and call me by my first name instead. I love humour, but when it’s done at other peoples expense not so much. That’s saved for people I don’t work with, or at least know very well. This guy had only been there a month.
I had the chance to work with scientists for a couple of years some time ago, and half the office addressed each other by by last name. It was different. I met some of the most interesting people, good times.
I work with all guys that are around my age, so the greetings are various vulgar insults.
The boss gets his first name though.
the judges are called ‘judge smith’ by non-judges, or just ‘judge.’ rarely ‘your honor.’ everyone else is first names. the judges call each other and all non-judges by first name. actually, i think it was yesterday that someone called me ‘shithead’, but i deserved it.
First names for everyone except the owner’s mother. She’s Mrs. Lastname. I can’t fathom calling her by her first name. I don’t even *know *her first name. She’s a sweet sweet lady, but the stereotypical Asian Tiger Mom, and I know better than to piss her off. It might be her son’s name on the paperwork, but she runs the place despite not even having a business card with her name on it.
Doctors (who aren’t part of my company, but we often have to call and work with) are generally Doctor Lastname, although a couple have asked to be called Doctor Firstname, or even just Firstname. I will cop to occasionally calling the doctors “Doctor”, mostly because I can’t be arsed to learn how to pronounce their names. Kaplan and Carney, no problem. But I’m not tearing my tongue in two over Sogbaike and Chalupzcak. Never know who’s going to be touchy about mispronunciation, so “Doctor” is safest.
My biggest problem is not knowing what to call the PAs (Physician Assistants). “Doctor Lastname” seems dishonest, but “Mister Lastname” seems rude.
I work in a hospital too. Everyone from CEO on down is firstname or nickname. Doctors are Dr. Lastname.
I think the only one who isn’t called by his first name is the CEO - everyone calls him Mr. P - his last name is a mouthful.
Usually by first name.
Friars have “Father” or “Brother” before their first name. The college president is Father <last name>, but only because his predecessor had the same first name; we’re starting to use the first name now that he’s been on the job for several years.
Depends on which colleagues. Those who are staff in my organization, even the MDs and Ph.Ds are referred to by their first names, and we all know each other well. Guest lecturers that I work closely with for a short amount of time (even those I work with repeatedly) are always Dr. so-and-so in my verbal and written communication.
Primarily first names, even with CEO’s, and some honorifics.
Firstnames or nicknames all the way in every company I’ve ever worked for (I’m in IT), except for one “competing first names” instance where one particular guy got tagged by his last name. This is Australia - we’re kinda like that. I doubt anyone much outside the military goes with surnames. Maybe police - not sure.
Slightly outside scope but… also, the kids all call their teachers by their first names these days. Except for Prep(=Kinder/=FYOS) which appears to be the last educational bastion of the honorific Mrs
