The Manufacturing & Energy sectors have long battled a perception problem: dated factories, rigid schedules, and career paths that plateau. But the employers winning top talent in 2026 are proving that people-first practices and advanced manufacturing aren't opposing forces — they're competitive requirements.
This year, Glassdoor launched our first-ever Best Companies in Manufacturing & Energy list as part of our 18th annual Best Places to Work awards. Interestingly, while manufacturing powerhouses dominate the top three spots, the category also features energy and infrastructure leaders such as climate innovator Trane Technologies (#7) and utility specialist Stake Center Locating (#8). Together, these winners are proving that regardless of the product, the ultimate competitive advantage is a well-supported workforce.
Let's look at what sets these winners apart, and what other employers can learn from their approach.
#1 Mars: How family-owned values scale in global manufacturing
Taking the #1 spot is Mars, a privately-held, family-owned giant known for its popular food, candy, and pet care brands. Despite its massive global scale, Mars has maintained a culture that feels personal. Employees consistently rate it highly for being a purpose-led company with caring leadership, proving that high-volume production and high-touch management can coexist.
Glassdoor reviewers praise the strong benefits and work-life balance that let them build long-term careers, not just jobs. The company is known for its "Five Principles” — Quality, Responsibility, Mutuality, Efficiency and Freedom — and those aren't just poster slogans. Employees say they genuinely feel encouraged to chart their own career paths with real support from leadership.
One new associate was struck by “Genuine people living their values” and a “Focus on career growth and networking, even within the first few weeks on the job.” Another praised the company’s “Excellent R&D environment,” where they have “Access to high-quality equipment/resources” and “Ample time to explore long-term research projects.”
Takeaway: Mars proves that family-owned values scale. When you build "freedom" into your operating principles — not just your HR manual — employees don't just execute; they innovate. The impact? Lower turnover in an industry plagued by workforce shortages, and the ability to attract mission-driven talent who would typically overlook manufacturing.
#2 Boston Scientific: Mentorship meets precision manufacturing
In the #2 spot is Boston Scientific, a global leader in medical technology. In an industry where precision is life-or-death, the company has distinguished itself by creating a culture where employees feel mentored rather than just managed.
Flexibility and work-life balance come up again and again in reviews — not exactly common in large-scale manufacturing. Employees also talk about how their daily technical work connects to life-changing medical outcomes. That sense of patient impact runs deep here.
A director raved that the company is, “Mission-driven with the patient at the center of all we do” and boasts a “Very innovative and supportive culture.” Another long-term employee stated unequivocally, “If YOU put in the effort and work, you WILL see a return.”
Takeaway: Boston Scientific's model shows that mentorship can't be an occasional check-in — it has to be part of how the work gets done. By connecting daily technical work to actual patient outcomes, they've made quality control feel personal instead of bureaucratic. Suddenly, compliance isn't just a checklist — it's something people take genuine pride in.
#3 GE Aerospace: Empowering engineers in high-stakes aviation manufacturing
Rounding out our top three is GE Aerospace. As a global leader in aviation, GE has weathered major industry shifts by doubling down on engineering excellence and putting its people first.
Reviewers consistently highlight leaders who back up growth promises with real support — mentorship, clear promotion paths, and strong benefits. It’s a rare combination that keeps engineers from jumping ship.
“I’ve worked at 3 other large aerospace companies and GE is by far the best that I’ve experienced,” praised one engineer, citing “work-life balance,” “team mentality between groups,” and “great bonus structure” among a long list of pros. A staff engineer with more than 10 years at GE highlighted, “Hard work leads to recognition and promotions.”
Takeaway: GE Aerospace shows that retention in highly technical fields comes down to trust and transparency. Merit-based promotions, real work-life balance, and a culture where teams collaborate instead of compete keeps engineers from job-hopping. In aerospace, where losing a senior engineer means losing years of irreplaceable knowledge, retention is paramount.
What this means for the Manufacturing & Energy workplace
These winners demonstrate that technology alone won't win the talent war. The best companies in 2026 have ditched the old factory-floor playbook in favor of cultures built on empathy and trust.
Here is what that looks like in practice:
- Connect work to real impact: People in manufacturing aren't motivated by hitting quotas alone — they want to see how their work matters beyond their workstation. Whether it's making life better for pets or powering life-saving medical devices, purpose turns a repetitive job into something meaningful.
- Build mentorship into the job itself: Boston Scientific and GE Aerospace prove that mentorship can't live in HR alone. When leaders actively coach their teams — not in scheduled check-ins, but in real time as the work happens — employees stop seeing a job and start seeing a career. This isn't about adding more meetings. It's about making feedback and development part of how work gets done every day.
- Rethink what flexibility means in industrial settings: It’s about respecting people's lives outside the plant. Predictable schedules. Compressed workweeks. Trust that people can manage their time without being micromanaged. This is what separates employers who retain talent from those constantly backfilling.
The best Manufacturing & Energy workplaces in 2026 aren't just making products — they're building places people want to stay.Want to see how your employer brand stacks up? Check out the full list of the Best Companies in Manufacturing & Energy 2026.
