What is union manufacturing?

Union manufacturing jobs are positions in the manufacturing sector where workers are represented by a labor union. These unions negotiate collective bargaining agreements with employers that cover wages, benefits, working conditions, and job security. Unionized manufacturing jobs are often associated with better pay, safer workplaces, and stronger protections against unfair treatment compared to non-union positions. Common examples include roles in automobile plants, steel mills, and electronics factories. Joining a union can provide workers with a collective voice to address workplace concerns and advocate for improved conditions.

What are the key skills and qualifications needed to thrive as a union manufacturing worker?

To thrive as a Union Manufacturing Worker, you need a solid understanding of production processes, safety protocols, and typically a high school diploma or equivalent. Familiarity with manufacturing equipment, assembly line systems, and often OSHA safety certifications are important technical requirements. Attention to detail, teamwork, and strong communication skills help distinguish top performers in this field. These competencies ensure safe, efficient production and foster positive labor relations within a collaborative unionized environment.

What are some common challenges faced by workers in a union manufacturing environment, and how are they typically addressed?

Workers in a union manufacturing environment often encounter challenges such as adapting to evolving production technology, meeting strict safety and quality standards, and coordinating with team members across shifts. To address these challenges, unions and management frequently collaborate on training programs, enforce clear safety protocols, and maintain open lines of communication through regular meetings. Additionally, union representation helps ensure that workers' concerns are addressed fairly, contributing to a supportive and organized work environment.

Machine Operators focus on operating machinery, often requiring technical skills. Both roles are integral to manufacturing industries, but union manufacturing typically offers additional benefits and structured work environments due to union involvement.

Job Description

Plant Engineering Manager

O'Fallon, MO

Build What's Next. Lead What Matters.

Are you a proven engineering leader who thrives in a fast-paced manufacturing environment? AFB is investing heavily in the future of our O'Fallon facility-and we're looking for a Plant Engineering Manager to lead safety, reliability, and operational excellence while shaping the next chapter of our plant's growth.

This is a high-impact leadership role where you'll influence people, processes, and capital investments that drive long-term success.

What You'll Do

As Plant Engineering Manager, you'll serve as a strategic and hands-on leader, responsible for plant reliability, safety, and continuous improvement:

  • Champion a safety-first culture, ensuring full compliance with OSHA, EPA, FDA, USDA, and environmental regulations.

  • Lead, coach, and develop a high-performing engineering and maintenance team in a unionized manufacturing environment.

  • Drive preventive and predictive maintenance strategies using CMMS systems to maximize uptime and equipment reliability.

  • Plan and execute capital and major expense projects, from budgeting and vendor management to commissioning and validation.

  • Partner with plant leadership to achieve Safety, Quality, Delivery, and Cost (SQDC) objectives.

  • Solve complex technical challenges across mechanical, electrical, and utility systems (compressed air, boilers, HVAC, water treatment).

  • Develop and manage operating and capital budgets, ensuring ROI, cost control, and alignment with plant goals.

What We're Looking For

We're seeking a confident leader with strong technical expertise and people-development skills:

  • Bachelor's degree in Engineering or a related technical field with 5-7 years of experience, or 15-20 years of equivalent hands-on experience.

  • At least 3 years of experience leading engineering and maintenance teams in a union manufacturing environment (or strong supervisory experience with a proven development track record).

  • Demonstrated success managing multi-million-dollar capital projects from concept through execution.

  • Deep knowledge of maintenance best practices, root cause analysis, vendor management, and CMMS systems.

  • Experience with continuous improvement methodologies such as Lean, Kaizen, or EBOS.

  • Strong communication skills with the ability to influence across all levels-from the shop floor to senior leadership.

  • Unwavering commitment to safety, compliance, and operational excellence.

  • Solid financial acumen with experience managing budgets and driving cost-effective solutions.

Preferred Experience

  • Engineering leadership experience in Food, Chemical, Pharma, or heavy industrial manufacturing.

  • Background working in fast-paced, unionized environments.

Why Join AFB?

  • Be part of a growth-focused organization investing in state-of-the-art upgrades, including new production lines, boiler installations, and wastewater system modernization.

  • Lead high-visibility projects that directly impact plant performance and long-term strategy.

  • Work in a collaborative, team-oriented culture alongside production, quality, and safety leaders.

  • Grow your career through continuous learning and development opportunities.

  • Enjoy competitive compensation and a comprehensive benefits package including health, dental, vision, paid holidays, vacation, and sick leave.
