When I first started working in Walmart’s OMNI department, I thought my biggest challenge would be learning where everything was in the store. I also expected a lot of physical work and walking. What I didn’t expect was the mental challenges that came with the job. I truly thought it was going to be a mindless job that was easy to do and I could come home and work online. I was wrong!
After a couple of months on the job, I’ve realized that working in OMNI is just as much a psychological exercise as it is a physical one. Every shift I learn something new about picking groceries, and also about how the human mind works under pressure.
Here are some of the biggest psychological lessons I’ve learned while in OMNI.
Your Brain Is Constantly Working
People often assume OMNI is simply walking through the store collecting groceries. In reality, your brain is doing a million things at once.
You’re looking for products, checking expiration dates, deciding whether produce is good enough, making substitution decisions, navigating around customers and other workers, watching your pick rate, dealing with grumpy co-workers, remembering staging procedures, and answering customer’s questions… a lot!
Talk about a cognitive load! Your brain has a limited amount of working memory, and in OMNI you’re asking it to process an incredible amount of information every minute.
It’s no wonder I come home mentally exhausted, especially during my first few weeks. I wasn’t just learning a job, I was asking my brain to build an entirely new system for processing information.
Every Shift Includes Thousands Of Little Decisions
Before working here, I never realized how many decisions personal shoppers make.
- Should I substitute this item?
- Is this watermelon ripe enough?
- Should I choose this package of strawberries or the one behind it?
- Is this yogurt close enough to the expiration date?
- Is this damaged enough to reject?
- Do I have time to go look for this item or should I NIL it?
Multiply those decisions by hundreds of items every shift.
By the end of the day, your brain has made thousands of judgments, many of them in just a few seconds. This is all about decision fatigue. The more decisions you make, the harder it becomes to make good ones.
That explains why even experienced associates can occasionally overlook something near the end of a long shift.
Comparing Yourself to Everyone Else Can Be Dangerous
One of the biggest psychological traps I fell into when I started was comparing myself to experienced coworkers. Oh… this was painful!
Some people seem to know exactly where every product is. They move quickly, rarely ask questions, and appear completely confident.
Meanwhile, I could barely find a product while looking straight at it!
Psychologists call this Social Comparison Theory. We naturally compare ourselves to others, but we usually compare our own struggles with everyone else’s finished product.
What I eventually realized is that I wasn’t seeing their first few months. I was only seeing the result of YEARS of experience. That helped me to stop comparing so much.
However, I find that OMNI places a lot of effort on comparison. They literally show you how you are doing for picking in comparison to the rest of your co-workers. And they actively reward people in front of others with recognition, pins, and employee of the month postings. To me this is crazy. We are supposed to be working together, but they keep us competing against each other and comparing ourselves to our coworkers.
Why Some Days Feel Amazing And Others Don’t
Some shifts seem to go perfectly.
Your pick rate is high.
Everything is in stock.
Your printer behaves.
Customers are friendly.
Other days, it feels like everything goes wrong.
You spend ten minutes looking for one item.
Everything is locked behind glass or with those little magnetic locks.
Your printer prints half off the sticker and then runs out of paper when you try to print again.
Half the products need substitutions.
Customers are absolutely disgusting towards you.
You run over your foot with your cart.
This unpredictability in how you will feel actually has a psychological explanation.
Our brains respond strongly to variable rewards. Because every pick walk is different, every shift feels different. You never know whether the next order will be easy or frustrating. When it’s good, it’s really good. When it’s bad… well, let’s just say I’ve spent some time crying uncontrollably at work.
Stress Spreads Faster Than You Think
I’ve also noticed how quickly emotions spread throughout the department.
If one person is frustrated, everyone else seems to get frustrated, especially when it’s the back room person.
If a team lead is calm, the entire atmosphere feels calmer.
Psychologists call this emotional contagion. Human beings naturally pick up the emotions of people around them, often without realizing it.
That’s made me appreciate coworkers who stay calm even during busy periods. Their attitude affects more people than they probably realize, especially mine. In fact, I have one coworker who is always happy. She sees the humor in things, she doesn’t put pressure on herself or others, and she smiles a lot. I try to interact with her the most to catch her emotions. When I’m around miserable people, I start to make mistakes and my energy slows down.
Your Brain Learns Faster Than You Think
Working in OMNI has made me realize how adaptable the brain really is.
During my first weeks, every aisle felt unfamiliar. I didn’t think I would ever learn the store.
Now, I often know exactly where something is before my handheld even finishes loading the location.
That’s because of something called neuroplasticity, which is the brain’s ability to build stronger neural pathways through repetition.
Every shift literally changes your brain. There’s a lot of repetition in your pick route, items you pick, and items out of place, and my brain has quickly picked up on that.
The things that once required intense concentration slowly become automatic and it’s soooo nice!
Feeling Included Matters More Than I Expected
Feeling accepted by your coworkers has a huge impact on how you experience your day.
When someone says good morning, offers help, or simply treats you like part of the team, it changes your confidence.
Likewise, moments when you feel left out or ignored can stay with you much longer than they should. This has happened a lot and I’ve had my share of tears around this too.
Psychologists have found that a sense of belonging affects confidence, learning, stress levels, and even job performance.
It’s a reminder that small acts of kindness at work aren’t actually small at all. And I try to be as kind as possible to others and make them feel included so they don’t feel left out.
Time Works Differently When You’re Focused
I’ve noticed that some shifts take forever, while others are over before I know it.
When everything is flowing smoothly, I’m completely focused on picking, making decisions, and moving efficiently.
Psychologists call this state flow.
It’s that feeling where you’re fully engaged in what you’re doing and lose track of time.
The more comfortable I’ve become in OMNI, the more often I find myself entering that state and my shifts seem to move much faster now.
I Think More Like An OMNI Picker Now
One funny thing I’ve noticed is that I don’t turn my OMNI brain off when I leave work.
I automatically notice store layouts.
I mentally organize products.
I even catch myself planning the fastest walking route through grocery stores.
It’s amazing how quickly your brain adapts after doing the same type of work every day.
It Really Is More Than Just About Steps In OMNI
When I accepted this job, I thought I was signing up for physical work. And I wanted that! I also thought I would get some cool stories to write about here.
What I actually signed up for was a crash course in psychology, and if you look around on this website, you will see how much I love learning and understanding how we work.
I’ve learned about attention, memory, decision-making, emotional resilience, confidence, and how quickly the brain can adapt to new challenges.
Working in Walmart OMNI has shown me that every customer only sees the finished product, which is their completed grocery order.
What they don’t see are the thousands of tiny mental decisions, constant problem-solving, and psychological challenges happening behind the scenes.
The more I learn about the psychology behind the job, the more respect I have for everyone who does it every day. Especially the ones who don’t complain!
