They should be unless you want to publish one of the things that too many (eg sites) regard as a reasonable secondary security verifier.
Insanity•1h ago
It depends on the culture/religion. Not everyone celebrates birthdays.

I had multiple ICs ask me not to say public birthday wishes, as they didn’t celebrate their birthday and/or did not want the rest of the team to know.

ghaff•54m ago
They're not really for many people (and, personally, I don't go to any extremes to keep it a secret). But sharing info like that from an HR record without permission feels a bit wrong even if others here obviously disagree.

A UK worker was awarded £25,000 by a tribunal for receiving an unwanted birthday card. Though it was merely the straw that broke the camel's back.

tetha•1h ago
I'm now somewhat interested in the study to see how they accounted for possible hidden factors.

If a team lead or manager spent the time to track birthdays and took time out of their day to have a 10 minute chat with someone on their birthday, they probably exhibit a number of other behaviors that could be summarized as "treating their employees as humans". That's the boss people tend to like to work with and possibly go another mile for them.

If tolerating your boss during a normal day takes 9 of your 12 spoons of energy for the day, it takes very little further push to be spiteful. At worst, they may force you to find another workplace with a better boss.

This seems obvious but I guess needs 'official research' to register.

A quote I remember from a coleage - 'They wouldn't give me a pay rate rise, so I gave myself one, by working less hours in a day'

freehorse•1h ago
Yeah, I think nobody is gonna tell their boss "I did not like the way you treated me, so I will take a day off for feeling slightly sick". So, while it all sounds obvious, the extent of "idgaf then" is not easy to quantify.

Lord-Jobo•1h ago
Lots of “no shit” in these comments makes me wonder how many VP level managers you guys have interacted with. Maybe it’s just my location, but this is one of those things that legitimately NEVER makes it through to upper managers.

When they tell their base managers to crack the whip and force them to give the whole “you are not working hard enough, tighten up. Shorter lunches, clock in 5 minutes early, etc” speech to the base employees, they will absolutely feel resentment and do LESS work, not more.

For more than one reason.

A quite small few will be pushed over the edge and spend their energy trying to find a new position altogether. But the impact of losing them and having an open position for months will have a huge impact. The impact of losing even a below average worker is nearly always underestimated by uppers who see their 200+ indirects as just numbers on an HR chart. And the employees who hop jobs over bad management are usually in the top half of performance, not bottom.

Another handful of over-achievers will realize that their “extra mile” approach is clearly being ignored or not having any effect, and simply become achievers. This alone can have an impact that outweighs any potential gain from whip cracking.

The one thing that nearly all employees will do when this happens though: talk to each other and bitch about it. This will tank morale yes, but it more literally just takes a bunch of time and energy. A very large distraction from the actual work.

I’ve seen this now at several jobs in a few fields. The negative impact is so much larger than I ever would have guessed starting out.

If you want to get more work out of the same workers, you cannot use negative reinforcement. It will backfire. Positive reinforcement is not bulletproof but rarely makes things WORSE.

Manage smarter not harder.

The bosses with half a brain do this only when the supply of labor is increasing relative to demand for labor. The bet is that the sufficient employees won’t have a choice to find a different job, and people that fail to maintain the new pace can be replaced with newer, and maybe even cheaper employees.

javier2•51m ago
Yup. We just lost our "slightly below average" developers, but he was a nice guy and tries to deliver. But they have been slow to replace him, and now we are likely looking at 3 months before a new hire will just be in place, plus the new hire will not have the three years worth of experience the other guy had, so their project will likely be slower than at it already was for the rest of the year.
doubled112•28m ago
I’d take “slightly below average but is generally good to work with and tries hard” over “genius asshole” almost any day. Few projects require the latter.

There’s also the problem with how useless so many are at their jobs with no way to be sure until its too late.

greenchair•4m ago
mostly agree but the below average try hard is also the one introducing the most bugs so I'm torn on this.

bagacrap•44m ago
Of course a small company of under 1000 employees is going to have a lower executive pay and therefore lower pay gap/ratio than a Fortune 500 company.

As someone who has a 401k, I certainly hope that the CEOs of our biggest companies are more highly compensated (~competent) than the CEO of Martin's Chicken Shack.

UK-Al05•35m ago
And yet the tolerance for bad decisions is much higher in bigger companies. Make a bad decision at large company and simple intertia will keep you going. Make a bad decision in a small company and you're out of business.

pinnochio•1h ago
There's a lot of jeering, I suspect at the headline more than anything, but having documented research can be helpful in changing management behavior. The changes in employee behavior documented here are not ones that managers would easily connect to their past behavior, such as a late birthday recognition.

When you train a dog, you have to give a reward very soon after the desired behavior, otherwise the dog won't associate the reward with the behavior. Likewise, a manager is not going to associate a slight towards an employee with an increase in absenteeism or lower productivity that happens days and weeks later.

mejutoco•1h ago
> When you train a dog, you have to give a reward very soon after the desired behavior, otherwise the dog won't associate the reward with the behavior

Regarding dog training, one can use a placeholder for the reward. This is useful, for example, if you want to reward a dolphin jumping through a hula, because you will not be able to give the reward at that moment, but for example, you can say "yes!" or use a clicker at that moment, and give the reward later, and it will be clear what caused it.

For anyone training any animal, I recommend the book: Don't Shoot the Dog! The New Art of Teaching and Training by Karen Pryor (not affiliated in any way)

pinnochio•57m ago
I suppose the employee-getting-revenge-on-manager equivalent would be playing some loud, annoying sound immediately after the slight, and then engaging in absenteeism and cutting work early later on.
njhnjhnjh•39m ago
What about cracking his skull with a hammer?
pinnochio•36m ago
I mean, that works too. Unless the resulting concussion, brain damage, or death means they don't make the association with their slight.
tarkin2•50m ago
Have we got to the point where we need an article telling us that slighting people doesn't help their motivation? Perhaps the answer is yes when we also compare a worker's motivation to a dog's motivation seemingly without irony.
pinnochio•43m ago
Having a documented effect and effect size puts this in terms that can change manager behavior, even a somewhat callous one, because they can see how it affects their own professional goals.

Btw, the comparison was between the dog and manager, and about the association of cause and effect. Maybe you should try to read more carefully and charitably in the future.

tarkin2•23m ago
Well, to many it seemed that an obvious cause-and-effect fact that should have come from empathy and introspection--that workers are just like you and I don't like being slighted--and didn't need to be written about.

Yet when of the top comments used dog training to explain manager-worker relations--something that empathy and introspection could tell you was a bit off (would you feel slighted if I make our interactions analogous to an owner and dog?)--it may show, yes, such does need to be spelt out these days.

I recall the University of Manchester was teaching university students empathy.

pinnochio•15m ago
Again, the comparison was between a dog and a manager. There's zero insinuation that a manager is like an owner and an employee like a dog. It does feel like you're looking for a pretext to feel slighted here.

That aside, I completely agree with you that managers should engage in empathy and introspection. I still think it's helpful, even for those that do, to have some empirical confirmation of how strongly employees can be affected by what might seem a simple oversight to an otherwise empathetic and introspective manager. But unfortunately, callous people tend to be chosen for management, and this research is also potentially helpful in aligning their own self-interest with their employees.

njhnjhnjh•43m ago
Many of the people who use this forum are terminally socially inept.

I don't mean that to be facetious. I mean that a small but significant portion of the people here will die because of their social isolation and inability to communicate effectively.

I thought it was interesting. Going through something like this myself right now, I learned that I don't lose motivation to do the work. I gain a motivation to cut the person out of the picture.

mejutoco•3m ago
I think you responded to the wrong post. I did not suggest or made any of these comparisons or comments. I simply recommended a book about training dogs or other animals, and the clicker method.

Engineering managers treat their dogs with greater respect than their employees.

From the further linked https://knowledge.wharton.upenn.edu/article/when-employees-f... -

> "They found the perfect observational setting in the retail chain, which has a well-established policy that managers hand-deliver a card and small gift to each employee on their birthday. The company designed the policy to foster meaningful personal interactions and strengthen the employee-manager relationship"

> "The team found no issues when cards and gifts were given within a five-day window of the employee’s birthday"

Part of me wonders more now if the slight also comes from the expectation of receiving a gift under this policy? If someone told me "hey, happy birthday, dude" that'd be good enough for me.

nsgi•1h ago
As a Brit, the birthday card example feels oddly American. The effect seems plausible, but the UK equivalent slight would be something much more informal
pinnochio•1h ago
I wonder if this is generationally specific. I'm an American and have zero expectation that anybody at work should acknowledge my birthday.

On the other hand, I can understand feeling slighted if the manager consistently recognizes their employees' birthdays but overlooks mine.

knallfrosch•55m ago
> the retail chain, which has a well-established policy that managers hand-deliver a card and small gift to each employee on their birthday.

> The faux pas was never intentional; the managers who were late said they had other priorities.

If it's such a well known company policy and you forget that, it is not a small slight at all.

jmyeet•36m ago
A lot of work is fake work. It's just social signaling. It's just a game of being liked. Just look at the stats for autistic people who have difficulty finding and maintaining employment, not because they're bad at their actual job but because neurotypical people just don't like them. Anyone who has worked for a remotely large organization has met plenty of people who have been promoted well beyond their actual abilities or output.

In this space you'll often hear about Dunbar's number [1] and the idea that organizations with more than about 150 people tend to break down. In larger organizations, a whole layer of middle management seems to rise up with questionable output. Like you might have no idea who your VP is. One place I worked had the VP visit once a quarter, walk aroudn and ask what people worked on and occasionally yell at them.

The military is an interesting example because it's millions of people, often in confined spaces so a whole bunch of rules have to be created so they don't kill each other, basically. And if you talk to any current or former servicemembers you'll hear stories about how not much gets done there either. Toxic leadership, lots of waiting around for nothing, bureaucracy and so on.

One can view this "research" as "be nice to your employees" but I think it's more nefarious than that. Or at least "be nice" won't be the lesson Corporate America takes from it. Instead it'll be that employees need to be even more closely monitored so they're not slacking off.

I think about what I call "organizational churn". This is where every 6 months you'll get an email saying a VP in your direct chain whom you've likely never met now reports to a different SVP under some restructure or reorganization to "align goals" or for "efficiency".

What you realize after awhile is that organizational churn only exists so nobody is every accountable for their actions or output. They're never in the same place long enough to see the consequences of their action or inaction.

But what I've thought about a lot recently in terms of organization is the Chinese Community Party. Millions of people work for the CCP. Yet it's output has been stunning. Some 40,000km of high speed train lines in 20 years for less than the US spends on the military in one year. Energy projects, metros, bridges, cities, housing, roads, ports, the list goes on.

How does the CCP avoid empire-building, institutional rot and general bureaucratic paralysis?

Oh they don't! In exactly the same way US didn't. Right now, a lot of factors have put enough tailwind into Chinese economy and the inertia is a bitch to retreat, as can be seen with US itself. These tailwinds are strong enough that they lift everybody up, even considering the corruption taking its share.

A good leader believes in the team and the team’s mission.

Celebrating birthdays and milestones are a possible side effect of this, but these celebrations can’t take place of the power of that belief.

If you consistently smile, you can force yourself to be happier, and if you force yourself to celebrate others, that’s still a good thing. But, your team will know if you don’t believe.

You’re better off being Gary Oldman in Slow Horses (only secretly believing in the mission and with a team that all care) than just being in it for the paycheck.

I’m not saying to quit if you can’t believe, but don’t expect top productivity.

hypeatei•1m ago
Maybe I'm a bit jaded, and corporate environments have taken their toll, but I see the employee-manager relationship as adversarial by default. Whether my boss wishes me happy birthday or not doesn't move the needle much. I'm there to contribute as an individual and he's there to answer to his boss about staffing, budgeting, and performance.

Although, I do feel slighted when a manager acknowledges the absurdity of all the corporatisms we hear everyday then proceeds to preach them to everyone and waste time anyway. Like, please, I thought we just agreed this is all fluff.
