For many industrial companies, the shortage of skilled workers is already part of daily business. According to the German Institute for Economic Research, there were over 530,000 job openings in October 2024. In industrial assembly, mechanical engineering, maintenance, electrical installation and plant relocation in particular, qualified specialists are often missing to complete projects reliably and on schedule.
If industrial mechanics, mechatronics technicians, electronics technicians, welders, fitters or project managers are not available, assembly projects quickly come under time and performance pressure. As a result, machines cannot be installed on time, production lines cannot be converted as planned and maintenance work is not completed on schedule.
The shortage of skilled workers does not only affect HR. It has direct consequences for production, delivery capability, costs, quality, innovation and competitiveness. This makes it important to look closely at the causes, impacts and possible solutions.
What does skills shortage mean?
A skills shortage means that companies can only fill vacancies with suitable qualified staff with great difficulty or at considerable effort. The problem is not just a lack of workers, but a lack of specific qualifications, professional experience or specialisations.
In industrial assembly, the skills shortage mainly affects technical professions. These include industrial mechanics, mechatronics technicians, electronics technicians, metalworkers, welders, plant fitters, mechanical engineers, hydraulics and pneumatics specialists and experts in automation technology.
Skills shortage or labor shortage: what is the difference?
Skills shortage and labor shortage are often used as if they mean the same thing, but they do not. A labor shortage means there is a general lack of workers for certain tasks, which can sometimes be done by trained or less specialised staff.
A skills shortage, on the other hand, concerns qualified employees with vocational training, a degree, professional experience or specific technical know-how. In industry this is particularly important, because many tasks cannot simply be taken over by unskilled workers.
Quantitative skills shortage
A quantitative skills shortage exists when there are generally too few qualified specialists available on the labor market. Companies then struggle to find applicants even when they offer attractive positions.
Qualitative skills shortage
A qualitative skills shortage exists when there are applicants, but their qualifications do not match the job requirements. This is common in industry, because digitalisation, automation, robotics and modern control technology create demand for new skills.
Why is industrial assembly particularly affected?
Industrial assembly is very hands-on and technically demanding. Many tasks require experience, manual skills, technical understanding and the ability to work safely on construction sites, in production halls or on running plants.
Assembly projects in industry are also often time-critical. Machines must be dismantled, relocated, installed or restarted during short shutdowns. This calls for well-coordinated teams and qualified specialists.
- Machine and plant assembly require technical expertise.
- Electrical installation and automation demand specific qualifications.
- Welding, hydraulics and pneumatics require experienced specialists.
- International assembly assignments call for flexibility and project experience.
- Modifications and relocations often have to be carried out within tight time windows.
Causes of the skills shortage in industry
The skills shortage has several causes that often interact. Especially relevant are demographic change, the declining appeal of technical professions, higher qualification requirements and the competition for skilled workers.
Demographic change
In the coming years, many experienced specialists will retire. At the same time, too few young people are choosing technical vocational training. This creates a gap between those leaving and those entering the workforce.
In industrial assembly this is particularly challenging, because much knowledge is gained over many years on the job. Experience with machines, plants, processes, safety and site organisation cannot be replaced quickly.
Declining appeal of technical professions
Many young people now prefer to study or choose careers outside industry. Technical apprenticeships are often seen as physically demanding, outdated or unattractive. This perception is usually inaccurate, but it still affects recruitment of new talent.
Yet technical professions in industry offer many development opportunities, a strong practical focus and an important role in areas such as automation, energy efficiency, mechanical engineering and Industry 4.0.
Rising demands due to digitalisation
Modern industrial plants are becoming more complex. Mechanics, electrical engineering, software, sensors, robotics and automation are increasingly interconnected. This raises the bar for specialist skills.
An industrial mechanic today often needs to understand interfaces with control technology, pneumatics, hydraulics or digital systems. Mechatronics technicians no longer work only on individual components, but increasingly on complete plant processes.
Fewer trainees
Many companies find it difficult to recruit apprentices for technical careers. If fewer young people are trained over many years, the skills shortage becomes more severe in the long term. Small and medium-sized enterprises feel this particularly strongly.
International competition for skilled workers
Qualified specialists are in demand worldwide. Other countries also seek technicians, engineers, fitters and experts for industrial projects. This intensifies competition for experienced personnel.
High workload in assembly jobs
Industrial assembly is often physically and organisationally demanding. Shift work, travel, tight deadlines or assignments in ongoing production demand a high level of resilience. Not everyone wants to work permanently under these conditions.
Which professions are in particularly high demand in industrial assembly?
In industrial assembly there is often a lack of specialists who work hands-on and understand technical contexts. The focus is on roles that are directly responsible for assembly, conversion, maintenance and commissioning of machines and plants.
Industrial mechanics
Industrial mechanics assemble machines, align components, check mechanical functions and support maintenance, repair and commissioning. They are indispensable in almost all areas of industrial assembly.
Mechatronics technicians
Mechatronics technicians combine mechanics, electrical engineering and control technology. They are particularly important for modern machines, automated plants and complex production systems.
Electronics technicians and electrical fitters
Electronics technicians and electrical fitters handle electrical connections, control cabinet work, wiring, testing and integration of technical components. Many machines and plants cannot be operated safely without them.
Welders and metalworkers
Welders and metalworkers are needed for steel structures, machine frames, adaptations, repairs and assembly modules. Their experience is especially valuable in plant conversions and custom solutions.
Hydraulics and pneumatics specialists
Many industrial plants use hydraulic and pneumatic systems. Specialists must understand pipes, valves, cylinders, pumps, compressed air systems and safety requirements and install them correctly.
Project managers and site managers
In addition to hands-on specialists, experienced project managers and site managers are often in short supply. They coordinate teams, schedules, interfaces and communication between client, production and assembly staff and ensure safe execution.
Industrial sectors most affected
The skills shortage impacts many industrial sectors. It is particularly noticeable in industries that rely on qualified workers, technical specialists and experienced assembly teams.
Mechanical engineering
Mechanical engineering needs specialists for development, production, assembly, maintenance and commissioning. If mechanics, electronics technicians or automation technicians are missing, machine projects and delivery dates are delayed.
Automotive industry
The automotive industry is undergoing change. E-mobility, battery technology, automation and new production concepts are reshaping skill requirements. At the same time, experienced fitters, maintenance staff and mechatronics technicians are still needed.
Electrical industry
The electrical industry lacks specialists for assembly, production, testing, automation and technical development. Electronics technicians, electrical engineers and control technology specialists are particularly sought after.
Metalworking
Metalworking companies need welders, machining technicians, machine operators, toolmakers and metalworkers. The shortage affects production, repair, custom builds and assembly.
Chemical and pharmaceutical industry
Chemical and pharmaceutical plants have high demands regarding safety, documentation and technical reliability. Specialists for plant assembly, maintenance, process engineering and technical testing play a key role here.
Food industry
In food production, equipment must operate reliably and meet strict hygiene standards. Specialists for maintenance, machine operation, servicing and plant conversion are crucial for stable production processes.
How the skills shortage affects companies
The skills shortage is more than a staffing issue. It has direct effects on production, projects, quality and costs. In industrial assembly, a lack of skilled workers quickly leads to problems.
Production delays and longer project durations
If qualified fitters or technicians are missing, machines cannot be installed, serviced or converted on time. Project schedules, commissioning and delivery dates are pushed back.
Rising costs
Companies must spend more on recruitment, overtime, shift work, external support or rework. Delays and production downtime can also cause significant additional costs.
Higher workload for existing staff
If vacancies remain unfilled, existing teams have to take on more tasks. This can result in overload, errors, sickness absence and lower motivation.
Quality risks
Time pressure and lack of experience increase the risk of assembly errors, rework or incomplete documentation. This can be particularly problematic for safety-critical plants.
Reduced capacity for innovation
Digitalisation, automation and modernisation all require qualified staff. Without them, technical improvements are implemented more slowly or postponed.
Threat to competitiveness
Companies that struggle to deliver projects reliably lose flexibility. This can damage customer relationships, delivery performance and long-term market position.
Approaches to tackling the skills shortage
The skills shortage cannot be solved with a single measure. Companies need a mix of training, further education, employee retention, digitalisation, better planning and external support.
Strengthening training
In-house training is one of the most important long-term levers. Companies should actively promote technical professions, offer internships, work with schools and show young people the development opportunities that industry provides.
Expanding further training and upskilling
Existing employees can be prepared for new requirements through targeted training. This includes courses in automation, PLCs, robotics, electrical engineering, hydraulics, pneumatics, occupational safety and digital documentation.
Improving employee retention
To retain skilled workers, companies need attractive working conditions. These include fair pay, predictable working hours, appreciation, development opportunities, modern equipment and clear communication.
Making work processes more efficient
Better planning, digital project management and clear standards ease the burden on existing specialists. Well-prepared workflows reduce waiting times, rework and unnecessary stress.
Using automation in a targeted way
Automation cannot fully replace specialists, but it can simplify repetitive tasks and relieve teams. In production, logistics, testing and assembly, digital systems help to reduce bottlenecks.
Integrating international skilled workers
International recruitment can help if it is well prepared. Key factors are language support, recognition of qualifications, structured onboarding, cultural integration and fixed contacts within the company.
Involving external specialists
When projects peak, time windows are tight or capacity is lacking, external support can help. Industrial assembly service providers supply experienced specialists and support assembly, conversion, maintenance, dismantling, reassembly and commissioning.
How external support can ease the skills shortage
External support is particularly useful when projects have to be completed at short notice or in-house staff are already working at full capacity. It cannot replace a long-term HR strategy, but it can bridge acute bottlenecks and stabilise projects.
This is especially important in industrial assembly, because many projects are time-critical. Machine downtime, plant relocations or conversions cannot be postponed indefinitely. External specialists help to keep schedules and avoid production losses.
Typical areas of deployment for external specialists
- Machine and plant assembly
- Dismantling and reassembly of production equipment
