How to Handle 5 Tricky Situations with Coworkers

Original image

Many of us see our coworkers more often than we do our significant others, and when you spend that much time with anyone, the occasional uncomfortable scenario is inevitable. “It's common for tricky situations to emerge in the workplace,” says Lori Scherwin, founder of career firm Strategize That. “In all situations, you have the ability to choose how you interpret it."

"Attitude matters, so keep a positive one,” Scherwin says. And take a moment to get your feelings in check before responding—you'll want to make sure you respond to the situation objectively and not emotionally. Then, follow this expert advice to handle the unpleasantness gracefully.


Let’s say you’re working on a project and your teammate drops the ball on a specific task. Your boss asks what happened and—perhaps out of panic—your colleague points to you.

It’s tempting to take the confrontational or defensive route and snap back at your coworker, but that can backfire. In this scenario you want to accomplish two things: Let your boss know you’re not to blame and let your coworker know he or she can’t get away with that manipulative behavior. “Most bosses are not stupid. For the most part, they know who is the one performing and who is the one taking the easy route,” says Branigan Robertson, an employee rights attorney.

Still, you may want to clear the air and it’s probably best to simply be direct. Robertson suggests approaching your coworker with a calm but authoritative suggestion. He suggests saying something along the lines of, “Hey, I’m not sure what’s going on but the boss is blaming me for this. This was your job. Let’s go to his office and clear this up so he knows we’re working [to correct things] as soon as possible."

By making it known that you're hip to your coworker's finger-pointing, he or she will be less likely to pass the blame in the future. If it does happen again, though, it might be time for a conversation with your boss. Just make sure you keep the meeting quick, professional, and blameless. Make it about a misunderstanding rather than an issue with your colleague, Robertson says.

Of course, there’s throwing you under the bus and then there’s bullying. If the situation is more severe, you may have to take further action. “If it becomes overly toxic or inappropriate, keep a paper trail and raise the issue immediately,” Scherwin says. “Everyone deserves to be treated with respect—so advocate for yourself.”


Hopefully you're not losing any sleep over lunch theft, but it can be frustrating if your food mysteriously disappears from the office kitchen. Robertson suggests leaving a public note or sending an email blast out to the entire department. He recommends keeping things light to begin with:

Dear Whoever Stole My Lunch,

I hope you really enjoyed my sandwich. Next time you are hungry, please let me know who you are so I can bring in a second sandwich and share it with you. I don’t like hungry coworkers.

If the scenario is truly egregious (it's happening every day, or you have specific dietary requirements), Robertson says you should skip the note and take it up with a manager or someone in HR. “If anyone is acting unethically— in any situation, whether in job tasks or stealing food—raise it with someone who can get it taken care of. Bad behavior should never be tolerated, regardless of how major or not it seems.”

This is about more than just a missing yogurt, Robertson says, it's about office culture. “It is critically important to work in an environment where people trust one another. It's all about character—so if you see someone acting out of line consistently, raise the issue.”


Workplace gossip is especially awkward when it comes from your boss. Not in the least because it may cause you to wonder what is said about you behind your back—and how that might affect your future with the company. Whatever the reason for the discomfort, you want to stop gossip and complaining in its tracks, even when it comes from the top.

You can approach the situation with either of two methods: zero affirmation or redirection. With zero affirmation, you resist responding to the gossiper's bait. “Never agree with them,” Scherwin suggests. “Keep a neutral footing. Complaining is contagious—do your part in stopping it in its course.”

If they don’t take the hint, politely try to redirect the conversation, Robertson suggests. “If your boss comes into your office and starts gossiping about one of your coworkers, quickly interrupt him or her and say, ‘Oh c’mon boss, you’re not paying me to chit chat about Paula’s love life, can we talk about tomorrow's meeting? I need your direction on how to present the numbers.”

It’s important to end the conversation as soon as you can. The longer your boss continues to gossip, the harder it is to nip it in the bud. And when you ask about a task, you shift the conversation’s direction back to work.


Some companies are completely transparent about salary and benefit information, but many aren’t. So a question about your pay may put you in an awkward position. While sharing this information is legal in most cases, Scherwin suggests first considering what could be lost or gained by doing so. “Personal and sensitive information can get misconstrued if shared and can unnecessarily create hostility,” she says. “On the flip side, it can give you ammo to negotiate for more.”

Only share when there’s trust, confidentiality, and you’re comfortable with how the information will be used, Scherwin says.


It’s frustrating when a colleague piggybacks on all your hard work. You may feel petty for wanting the credit, but it's reasonable to seek recognition when you've put time and effort into a project. The best way to keep this behavior at bay is to keep a record of your tasks.

“Keep an e-mail record and be on guard with this coworker,” Scherwin says. “Take responsibility for sending the final product to the boss. Make sure you are actively discussing your ideas and progress across your organization so your role is clear before it's too late.”

As with trying to pass the buck, most bosses know what’s going on and may be more aware of the situation than you realize. Still, it can help to keep them updated on your progress. “Stay in communication with the person you want credit from [while you work]," Robertson says. "Tell them about what you are doing while you do it.”

This way, not only will your boss know the truth if a coworker tries to take credit for your work down the road, but if your coworker does take credit, your boss will see right through it and the situation will take care of itself.

Stickier, though, is your boss taking credit for your work. This may be a sign that your boss feels threatened by you; a confident manager typically has no problem supporting their team. “They may only be looking out for themselves and not be giving you as much ‘air time’ with senior management which would help you get future promotions,” Scherwin says. “Alternatively, they may also not even realize that this is impacting you. Always handle tricky boss conversations maturely. Take the emotion out of it. Rather than getting upset and demanding more credit, simply tell them you enjoy what you are doing and want more visibility, and ask them to work with you to make that happen.”

In other words, you want to make your manager part of the solution, she adds, rather than make it seem like they’re a problem. Workplace scenarios can be tricky to navigate and that seems to be the answer for most of these: Focus less on the problem and more on the solution and you’ll be on your way to a congenial workplace.

Man Buys Two Metric Tons of LEGO Bricks; Sorts Them Via Machine Learning

Jacques Mattheij made a small, but awesome, mistake. He went on eBay one evening and bid on a bunch of bulk LEGO brick auctions, then went to sleep. Upon waking, he discovered that he was the high bidder on many, and was now the proud owner of two tons of LEGO bricks. (This is about 4400 pounds.) He wrote, "[L]esson 1: if you win almost all bids you are bidding too high."

Mattheij had noticed that bulk, unsorted bricks sell for something like €10/kilogram, whereas sets are roughly €40/kg and rare parts go for up to €100/kg. Much of the value of the bricks is in their sorting. If he could reduce the entropy of these bins of unsorted bricks, he could make a tidy profit. While many people do this work by hand, the problem is enormous—just the kind of challenge for a computer. Mattheij writes:

There are 38000+ shapes and there are 100+ possible shades of color (you can roughly tell how old someone is by asking them what lego colors they remember from their youth).

In the following months, Mattheij built a proof-of-concept sorting system using, of course, LEGO. He broke the problem down into a series of sub-problems (including "feeding LEGO reliably from a hopper is surprisingly hard," one of those facts of nature that will stymie even the best system design). After tinkering with the prototype at length, he expanded the system to a surprisingly complex system of conveyer belts (powered by a home treadmill), various pieces of cabinetry, and "copious quantities of crazy glue."

Here's a video showing the current system running at low speed:

The key part of the system was running the bricks past a camera paired with a computer running a neural net-based image classifier. That allows the computer (when sufficiently trained on brick images) to recognize bricks and thus categorize them by color, shape, or other parameters. Remember that as bricks pass by, they can be in any orientation, can be dirty, can even be stuck to other pieces. So having a flexible software system is key to recognizing—in a fraction of a second—what a given brick is, in order to sort it out. When a match is found, a jet of compressed air pops the piece off the conveyer belt and into a waiting bin.

After much experimentation, Mattheij rewrote the software (several times in fact) to accomplish a variety of basic tasks. At its core, the system takes images from a webcam and feeds them to a neural network to do the classification. Of course, the neural net needs to be "trained" by showing it lots of images, and telling it what those images represent. Mattheij's breakthrough was allowing the machine to effectively train itself, with guidance: Running pieces through allows the system to take its own photos, make a guess, and build on that guess. As long as Mattheij corrects the incorrect guesses, he ends up with a decent (and self-reinforcing) corpus of training data. As the machine continues running, it can rack up more training, allowing it to recognize a broad variety of pieces on the fly.

Here's another video, focusing on how the pieces move on conveyer belts (running at slow speed so puny humans can follow). You can also see the air jets in action:

In an email interview, Mattheij told Mental Floss that the system currently sorts LEGO bricks into more than 50 categories. It can also be run in a color-sorting mode to bin the parts across 12 color groups. (Thus at present you'd likely do a two-pass sort on the bricks: once for shape, then a separate pass for color.) He continues to refine the system, with a focus on making its recognition abilities faster. At some point down the line, he plans to make the software portion open source. You're on your own as far as building conveyer belts, bins, and so forth.

Check out Mattheij's writeup in two parts for more information. It starts with an overview of the story, followed up with a deep dive on the software. He's also tweeting about the project (among other things). And if you look around a bit, you'll find bulk LEGO brick auctions online—it's definitely a thing!

200 Health Experts Call for Ban on Two Antibacterial Chemicals
Original image

In September 2016, the U.S. Food and Drug Administration (FDA) issued a ban on antibacterial soap and body wash. But a large collective of scientists and medical professionals says the agency should have done more to stop the spread of harmful chemicals into our bodies and environment, most notably the antimicrobials triclosan and triclocarban. They published their recommendations in the journal Environmental Health Perspectives.

The 2016 report from the FDA concluded that 19 of the most commonly used antimicrobial ingredients are no more effective than ordinary soap and water, and forbade their use in soap and body wash.

"Customers may think added antimicrobials are a way to reduce infections, but in most products there is no evidence that they do," Ted Schettler, science director of the Science and Environmental Health Network, said in a statement.

Studies have shown that these chemicals may actually do more harm than good. They don't keep us from getting sick, but they can contribute to the development of antibiotic-resistant bacteria, also known as superbugs. Triclosan and triclocarban can also damage our hormones and immune systems.

And while they may no longer be appearing on our bathroom sinks or shower shelves, they're still all around us. They've leached into the environment from years of use. They're also still being added to a staggering array of consumer products, as companies create "antibacterial" clothing, toys, yoga mats, paint, food storage containers, electronics, doorknobs, and countertops.

The authors of the new consensus statement say it's time for that to stop.

"We must develop better alternatives and prevent unneeded exposures to antimicrobial chemicals," Rolf Haden of the University of Arizona said in the statement. Haden researches where mass-produced chemicals wind up in the environment.

The statement notes that many manufacturers have simply replaced the banned chemicals with others. "I was happy that the FDA finally acted to remove these chemicals from soaps," said Arlene Blum, executive director of the Green Science Policy Institute. "But I was dismayed to discover at my local drugstore that most products now contain substitutes that may be worse."

Blum, Haden, Schettler, and their colleagues "urge scientists, governments, chemical and product manufacturers, purchasing organizations, retailers, and consumers" to avoid antimicrobial chemicals outside of medical settings. "Where antimicrobials are necessary," they write, we should "use safer alternatives that are not persistent and pose no risk to humans or ecosystems."

They recommend that manufacturers label any products containing antimicrobial chemicals so that consumers can avoid them, and they call for further research into the impacts of these compounds on us and our planet.
