Pros

Company pays 100% insurance premiums. Pay is decent. Gives an end-of-year profit sharing bonus (from one to five month’s salary, depending on company performance and employee tenure). Pays 100% tuition, including books, for any class at an accredited institution (i.e. MBA, PhD, cooking, etc).

Cons

Supervisors micro-manage; they obsess over, and penalize for, every tiny insignificant detail. However, reviews are highly subjective. If the supervisor likes you personally, you’re gold; if not, you’re out. The only ‘feedback’ you get is negative, because the company doesn’t waste time telling you what you’re doing correctly. They tend to favor negative reinforcement policies. Communication is terrible and inconsistent, and the rules seem to change every few days. Only those who are 22-25-ish, and from “prestigious” schools, get to be supervisors and managers (what they call the Management Development (MD) program), and even then, you must be recruited into this program as an external applicant. All others: give up any thought of being taken seriously or being promoted. You are expendable, as evidenced by the revolving door of new hires and fires, which makes it difficult to keep up with who still works there and who doesn’t. Reality: those who have advanced degrees and/or real world experience are placed in line-level positions and supervised by the aforementioned 20-somethings. Promotions from within (for line-level to management) are exceptionally rare. Open supervisor/management positions aren’t posted, so you can’t even apply for them. The company decides who it wants to be in those slots (from among those in the MD program), and usually with only a one-day notice. Line-level employees are often moved from department to department with little or no notice, and even within departments, employees are moved from supervisor to supervisor. Since each supervisor is different, it’s very difficult for an employee to adjust to the new style. They have no idea what the word ‘leader’ means, and really no idea there’s a difference between managing and leading, but that’s what happens when you put 22-year-olds in charge who have no real world experience. I’ve found a high degree of arrogance among many of them. Office employees aren’t allowed to decorate their cubicles (with the exception of a calendar and maybe one personal item), so you can’t tell if someone is just gone for the day or doesn’t work there anymore. Warehouse workers can decorate their lockers. No 401(k). Instead, company pays into their own fund for you. This sounds great, but you have to work six years to get vested, you can’t add your own contributions to it, and you can’t roll over a pre-existing 401(k) into it. If you aren’t hired into the MD program, using the benefit of 100% tuition to get an advanced degree won’t help you get promoted out of line-level. It’s ironic they’ll pay for your education, but won’t let you do anything with it. Many people use McM to pay for their degree, then quit and put it to use at a better company. Overall: toxic work environment and terrible corporate culture, which starts from the top. It isn’t worth selling your soul for a few dollars. Definitely not a good long-term career, unless you want to be bored your entire life. The short version: Run away. Run far. Run fast. I’m doing my best to provide an accurate review based on my personal experience, but if you doubt me, check out the hundreds of other similar reviews. I agree some may be sour grapes from disgruntled employees, but we can’t all be making this up. Note there is a big difference between reviews from line-level and management, as well as the different locations, which department you’re in, and who your supervisors are.

Pros

I met a small handful of really great coworkers here. Apart from that, the only pro is the free healthcare, the year-end bonus, and the inflated salary. Really though, you earn every penny.

Cons

Where does one start? This company is weird. They've managed to turn white-collar work into a blue-collar process. No one person knows anything about the company beyond their own role. Only the highest levels of management seem to know what the company trajectory is, though most of the time I felt like even the branch directors were making it up as they went along. And the lower down the chain of command you go, the less and less people seem to know and yet they're in charge of entire departments. Because of this, the department focus or direction frequently changes. And so starts the endless cycle of blame and "feedback." This company puts such an emphasis on "feedback" that it has created a toxic environment of endless criticism, undermining behavior, passive aggressive attacking, and a habit of pushing the blame off on someone else. It's so bad that you go into work expected to hear nothing but backhanded, rude remarks that subtly question your intelligence. And when you don't get that "feedback" you're actually surprised and mildly worried about it because when the "feedback" stops, they've usually already decided you're going to be shown the door. There is next to no positive reinforcement which only makes you feel like your work isn't valued. The work is already mindless crap that could have been automated ages ago. The company doesn't reward good work even though some employees have been there for DECADES. You will not be given more responsibility, you will not be promoted if you're a regular "business operations specialist" and you will be carelessly transferred to another department when the mood strikes a supervisor or manager and have that lateral move described as a "good thing." It's not. They just needed you in that department because they probably just fired the last guy. This company is clogged with management. They're constantly parading more and more candidates through the office who are interviewing for the "management trainee" program. Almost all of them are soon to be college graduates from highly recognizable universities (though this seems to be changing because more and more of these top tier candidates seem to be turning them down, according to a manager.) These Management trainee college grads are immediately given supervisor positions (though usually in the warehouse or the text contact department) and expected to know how to motivate and lead employees, with next to no work experience let alone leadership experience. They all inevitably fall into the habit of parroting the more "experienced" managers and fall back on nit picking and criticizing every little thing an employee does in a sad attempt to justify their pointless position and make it seem like they're "managing." I guess it's nice to hear when a genuinely incompetent manager is demoted back to a supervisor role and eventually shown the door. None of the "skills" are transferable. You learn nothing and they do this intentionally. If this is your first job out of college, know that you are royally screwed if you want to leave. Your work is meaningless and the sad fact is that any company worth working for will be able to see that on your resume. Before you think I'm some sort of disgruntled employee that was fired or let go, I left voluntarily. I knew this wasn't the place for me after six months and carefully set money aside in case they went through a random round of firings. I casually searched for a new position and when the right one came up, with a better salary and better opportunities, I took it and ran as fast as I could and haven't regretted it once.

Pros

None felt totally blindsided by this program

Cons

Before we begin, BEWARE the fake 5 star reviews, the McMaster recruiting team plants these due to years of negative feedback but still hilariously a 2.5 RATING. McMaster-Carr is always posting for the Management Development Program. Always. High salary, top schools, lots of openings. You should be asking yourself why a company this size has a permanent fire hose of recruitment going. The answer is turnover. They need a constant pipeline because people don’t stay. They pitch you on rotating through “business verticals” and building broad business acumen. What that actually means: operations track, you’re opening a warehouse at 7 AM an hour and a half outside Chicago and closing it at 7 PM. You’re getting home at 9. Every day. For a year. The other track people try to escape to is “systems.” That’s IT support. I’m not being reductive — that is literally what it is. A girl who went to Stanford ended up on IT. That’s the program. The tuition reimbursement thing is genuinely predatory. They dangle it like it’s this huge benefit. But you’re working 7 to 7 five days a week, so the only realistic option is a part-time MBA with night classes. And here’s the kicker — because they’re paying for it, they expect more out of you, work you harder, and eventually just fire you. Now you’re mid-program, part-time, and can’t switch to full-time because those are entirely separate applications. You’re stuck finishing a part-time MBA with no path into consulting or banking, maybe landing a PM role if you’re lucky, except those are disappearing fast. You end up in debt with a degree that didn’t open the doors you needed. There is no good outcome here. After operations, a lot of people end up in recruitment. Your job is to go back to your school and sell this program to your peers. Your college friends are starting at banks, joining startups, going to law school. You are cold messaging underclassmen on LinkedIn about profit sharing at a bolt company. That’s a real thing that happens to real people here. The culture is nonexistent. No events, no happy hours, no trips, no merch, no free snacks, you pay for lunch. The cafeteria food is bad and the smell is something else. The office is inside a warehouse off a highway. There is no outdoor space, nowhere to go decompress. You will never see or hear from the CEO. Not a video, not an all-hands, nothing. There is no identity to this place. Look at the faces when you walk around. It tells you everything. All bathrooms are shared — office staff, sales, warehouse workers coming off physical shifts, everyone. Nothing against warehouse workers at all, that’s not on them. But it’s a lot. The profit sharing doesn’t kick in meaningfully until around 1.5 years. Most people are gone before then. That math is not a coincidence. Survival guide if you have absolutely no other choice: 1. Get a car. This is non-negotiable. The shuttle to the train is unreliable, sometimes overfilled, and you may just be standing there waiting after an already brutal day. With a car you can actually leave at lunch — drive somewhere, sit in a parking lot, eat in silence, be a human being for 30 minutes. If team is on PTO or days when no one’s watching you can slip out for a bit and come back. That car is your only real freedom in this job. 2. The basement bathrooms are the cleanest. Use those. It also gives you a reason to walk, burn five minutes, and get out of your immediate environment. You take wins where you can find them. 3. Don’t work hard, it’s a retirement home. No Macs, extremely outdated hardware, and half the systems are broken. This isn’t a tech company, it’s a patch-and-pray operation. People get fired mid-project constantly so you end up inheriting half-built things with no documentation and no one to ask. Set your expectations accordingly — you are not building anything, you are duct-taping things that should have been replaced years ago. 4. Week one is your only window. They’re on good behavior and don’t want you to quit quietly before you’re useful to them. That’s the one moment you have any leverage internally. If you went to a school they want for recruitment purposes, you can try to negotiate a team switch. Ninety-five percent chance they say no, but that week is the only time it’s even worth asking. 5. Read your manager fast. You will know within two weeks if you have a weird one. Trust that instinct immediately — don’t talk yourself out of it. The people worth finding are the rare few who also understand exactly what this place is, have their own exit already mapped out, and are willing to quietly help you navigate it. They exist. Find them early, don’t broadcast it, and let them show you how to make this survivable. 6. Start GMAT prep on day one. Keep every external connection you have alive. Write down everything you do with numbers attached — you’ll need to make warehouse logistics sound like leadership experience on applications. And find a therapist before you need one. 7. Apply somewhere else. Anywhere else.​​​​​​​​​​​​​​​​
