Prof John Mubangizi, Dean of the Faculty of Law, encouraged delegates at the Fifth Annual International Mercantile Conference to share ideas on best international practice in their various fields.
“Don’t say anything online that you wouldn’t want plastered on a billboard with your face on it.”
This famous quote by international tech expert Erin Bury should be a guiding light when it comes to online habits in the workplace, according to Francois Cilliers, UFS Lecturer in Mercantile Law.
In his presentation Could Social Media be the Gateway to Employment Discrimination? he warned that employees have a responsibility not to bring their employers in disrepute through their comments on social media.
“Posts, updates, tweets, and comments are considered to be publications and can therefore never be seen as privileged information,” he explained.
Responsibility on employees and employers alike
He pointed out that employers also had a responsibility regarding the way in which they use the information about prospective employees obtained via social media.
“Nowadays, approximately 75% of companies hire through social media. In the US, recruiting companies spend hours researching candidates, making full use of what they can find on social media. It was found that 50–80% of employers frowned upon posts and pictures featuring drug and alcohol abuse, profanity, and bad grammar.”
He warned that employers needed to tread lightly, as a decision not to employ someone as a result of information on the prospective employee’s political views and sexual orientation could constitute unfair discrimination as set out in the Employment Equity Act.
“An employer who wishes to use a screening process (utilising social media) has to prove that the information and the process is objectively necessary and can be justified with reference to the inherent requirements of the job,” he explained.
“As technology and electronic systems advance, so too should the applicable labour laws.”
Cilliers’ presentation formed part of the Fifth Annual International Mercantile Law Conference recently hosted by the Faculty of Law on the Bloemfontein Campus.
Incorporating new technology in teaching and research
“This conference is an opportunity to share ideas on best practice in what is perceived as a ‘difficult’ field within Law,” said Prof John Mubangizi, Dean of the Faculty of Law, as he opened the proceedings. Topics in the discussion sessions ranged from Racism in the workplace and The underrepresentation of females in the judiciary, to Decriminalisation of cannabis: A recipe for healthy employer-employee relations?
“Conferences such as these help us to take advantage of the newest developments in technology to advance our teaching and research,” said Prof Mubangizi.
“To quote Einstein: ‘We can’t solve problems by using the same kind of thinking we used when we created them.’”
Researcher works on finding practical solutions to plant diseases for farmers

Plant disease epidemics have wreaked havoc for many centuries. Notable examples are the devastating Great Famine in Ireland and the Witches of Salem.
Plant diseases form, due to a reaction to suitable environments, when a susceptible host and viable disease causal organism are present. If the interactions between these three factors are monitored over space and time the outcome has the ability to form a “simplification of reality”. This is more formally known as a plant disease model. Lisa Ann Rothman, a researcher in the Department of Plant Sciences at the University of the Free State (UFS) participated in the Three Minute Thesis competition in which she presented on Using mathematical models to predict plant disease.
Forecast models provide promise fighting plant diseases
The aim of Lisa’s study is to identify weather and other driving variables that interact with critical host growth stages and pathogens to favour disease incidence and severity, for future development of risk forecasting models. Lisa used the disease, sorghum grain mold, caused by colonisation of Fusarium graminearum, and concomitant mycotoxin production to illustrate the modelling process.
She said: “Internationally, forecasting models for many plant diseases exist and are applied commercially for important agricultural crops. The application of these models in a South African context has been limited, but provides promise for effective disease intervention technologies.
Contributing to the betterment of society
“My BSc Agric (Plant Pathology) undergraduate degree was completed in combination with Agrometeorology, agricultural weather science. I knew that I wanted to combine my love for weather science with my primary interest, Plant Pathology.
“My research is built on the statement of Lord Kelvin: ‘To measure is to know and if you cannot measure it, you cannot improve it’. Measuring the changes in plant disease epidemics allows for these models to be developed and ultimately provide practical solutions for our farmers. Plant disease prediction models have the potential ability to reduce the risk for famers, allowing the timing of fungicide applications to be optimised, thus protecting their yields and ultimately their livelihoods. I am continuing my studies in agriculture in the hope of contributing to the betterment of society.”
