“…Job and organisational design literature have revealed various job demands that are positively related to turnover intentions, including disproportionate workload (i.e., Houkes et al, 2003 ), role stressors associated with performing tasks not in the employee’s job description or role ambiguity (i.e., Asiwe et al, 2015 ), and a lack of challenge (i.e., Mathieu and Zajac, 1990 ) characterised by task repetitiveness and excessive routine (i.e., Griffeth et al, 2000 ). According to Asiwe et al (2015) , excessive workload or high demands may also occur when an individual does not have the required skills, abilities and support to meet the expressed demands. High levels of stress are, therefore, prevalent in individuals experiencing work overload ( Schaufeli and Bakker, 2004 ), characterised by feeling overwhelmed by perceived time pressures and deadlines, excessive work demands and information overload ( Montgomery et al, 2003 ).…”
