Opinion article by Carmine Nieman, Industrial Psychology Lecturer at the University of the Free State.


Burnout – a widely recognised concept – has gained attention since its inception in the 1970s. Research has shown that burnout occurs when individuals exhaust their coping resources due to work and personal life demands, resulting in decreased job performance and extreme fatigue. Further review revealed that burnout often results from overworking and striving for perfection, particularly in high-pressure environments with challenging professional relationships. Though not officially recognised in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5), the literature defines burnout as a combination of emotional exhaustion, depersonalisation, and reduced personal accomplishments due to chronic work-related stress. This condition is identifiable through symptoms such as profound fatigue, loss of motivation, cynicism towards one's work, and a sense of inadequacy. Recognising burnout as a contemporary societal challenge is vital; however, in many countries, the official statistics on this topic are not even available. 

According to the literature, there are two coping strategies: positive coping, involving problem-solving and constructive appraisal, and negative coping, which leans towards managing emotions and adopting less effective coping mechanisms. Research has identified a positive correlation between negative coping and burnout, contributing to the experience of burnout among staff members who are struggling to cope personally or professionally. Stress and anxiety have inevitably also been a challenge at the University of the Free State (UFS) for years. Recent research reveals a strong link between stress and burnout, with job burnout identified as a risk factor for anxiety and stress. Thus, addressing job burnout is essential to reduce anxiety and stress symptoms among staff at the UFS, especially as we commemorate World Mental Health Awareness Month.

Mitigating the risk of burnout

Implementing early detection methods is essential to alleviate the adverse effects of burnout. Research underscores the significance of well-being in the workplace, covering emotional, psychological, physical, and behavioural aspects, to effectively manage and prevent burnout. Additionally, burnout has repercussions on personal life, leading to family issues, work-life conflict, and a diminished quality of life, underlining the importance of social support. Preventing and managing burnout entails both individual and organisational strategies. While organisations bear some responsibility, it is unrealistic to expect employees to relinquish personal responsibilities entirely. 

There are numerous research outcomes based on individual strategies. Individual strategies encompass role and boundary management, cognitive restructuring, time management, lifestyle balance, coping strategies, work pattern adjustments, social resource utilisation, and overall well-being and self-assessment. Cognitive restructuring effectively prevents burnout by transforming negative and irrational thought patterns into positive and constructive ones. Time management and planning are core skills for managing a demanding job. Lifestyle management – the balance between work and non-work roles – is increasingly relevant. Moreover, effectively coping with stress by managing thoughts and controlling the interpretation of stressful experiences helps prevent and manage burnout symptoms. Furthermore, changing work patterns is recommended, such as taking regular breaks and avoiding excessive overtime. Leveraging social resources, including support from supervisors, colleagues, family, and friends, is also vital to prevent burnout.

The organisation’s social responsibility role

Research-based strategies on the organisational level are less than on the individual level but offer valuable advice and recommendations. Organisations can contribute to burnout prevention by implementing and developing policies and initiatives. Organisations should focus on transitioning individuals from burnout to engagement by fostering energy, resilience, involvement in work tasks, and job success. Regular well-being assessments also provide insights into individual and organisational well-being and coping. Supportive organisational strategies to prevent burnout entail role clarification, goal setting, nurturing supportive management relationships, eliminating unnecessary stressors, and offering flexible work schedules. Other organisational strategies include supportive practices, job design, coaching, and wellness programmes such as those offered by the Division of Organisational Development and Employee Well-being.

Based on the cumulative insights, an effective approach to addressing and preventing burnout on both individual and organisational levels involves enhancing personal and workplace coping skills. This can be achieved by replacing negative thought patterns with constructive patterns using rational emotive behaviour therapy techniques. Additionally, implementing constructive thinking techniques towards a model that focuses on various aspects of work life can assist in managing and preventing burnout. Furthermore, implementing early detection strategies is pivotal in identifying potential issues before they escalate.

Ultimately, a combined treatment plan involving collaboration between the organisation, industrial psychologists, and individuals is recommended. Such an approach ensures effective burnout management, focusing on well-being and minimising the impact of burnout.

In conclusion, burnout is a significant concern with implications for individuals and organisations. Effective interventions and treatment plans are pivotal for safeguarding well-being. Future research should continue to explore and develop treatment plans to enhance the success and well-being of individuals and organisations.

Researcher part of project aimed at producing third-generation biofuels from microalgae in Germany

A researcher from the University of the Free State (UFS), Prof Johan Grobbelaar, was invited to join a group of scientists recently at the Institute for Bio- and Geo-Sciences of the Research Centre Jülich, in Germany, where microalgae are used for lipid (oil) production, and then converted to kerosene for the aviation industry.

The project is probably the first of its kind to address bio-fuel production from microalgae on such a large scale.  

“The potential of algae as a fuel source is undisputed, because it was these photoautotrophic micro-organisms that were fixing sunlight energy into lipids for millions of years, generating the petroleum reserves that modern human civilisation uses today.  However, these reserves are finite, so the challenge is marrying biology with technology to produce economically-competitive fuels without harming the environment and compromising our food security.  The fundamental ability that microalgae have to produce energy-rich biomass from CO2, nutrients, and sunlight through photosynthesis for biofuels, is commonly referred to as the Third-Generation Biofuels (3G),” said Prof Grobbelaar.

The key compounds used for bio-diesel and kerosene production are the lipids and, more particularly, the triacylglyserols commonly referred to as TAGs.  These lipids, once extracted, need to be trans-esterified for biodiesel, while a further “cracking” step is required to produce kerosene.  Microalgae can store energy as lipids and/or carbohydrates. However, for biofuels, microalgae with high TAG contents are required.  A number of such algae have been isolated, and lipid contents of up to 60% have been achieved.

According to Prof Grobbelaar, the challenge is large-scale, high-volume production, since it is easy to manipulate growth conditions in the laboratory for experimental purposes.  

The AUFWIND project (AUFWIND, a German term for up-current, or new impetus) in Germany consists of three different commercially-available photobioreactor types, which are being compared for lipid production.

The photobioreactors each occupies 500 m2 of land surface area, are situated next to one another, and can be monitored continuously.  The three systems are from Novagreen, IGV, and Phytolutions.  The Novagreen photobioreactor is housed in a glass house, and consist of interconnected vertical plastic tubes roughly 150 mm in diameter. The Phytolutions system is outdoors, and consists of curtains of vertical plastic tubes with a diameter of about 90 mm.  The most ambitious photobioreactor is from IGV, and consists of horizontally-layered nets housed in a plastic growth hall, where the algae are sprayed over the nets, and allowed to grow while dripping from one net to the next.

Prof Grobbelaar’s main task was to manipulate growth conditions in such a way that the microalgae converted their stored energy into lipids, and to establish protocols to run the various photobioreactors. This was accomplished in just over two months of intensive experimentation, and included modifications to the designs of the photobioreactors, the microalgal strain selection, and the replacement of the nutrient broth with a so-called balanced one.

Prof Grobbelaar has no illusions regarding the economic feasibility of the project.  However, with continued research, optimisation, and utilisation of waste resources, it is highly likely that the first long-haul flights using microalgal-derived kerosene will be possible in the not-too-distant future.

Prof Grobbelaar from the Department of Plant Sciences, although partly retired, still serves on the editorial boards of several journals. He is also involved with the examining of PhDs, many of them from abroad.  In addition, he assisted the Technology Innovation Agency of South Africa in the formulation of an algae-biotechnology and training centre.  “The chances are good that such a centre will be established in Upington, in the Northern Cape,” Prof Grobbelaar said.
