What it’s about

In a world where retaining top talent is paramount, how can organizations most effectively invest their human resources budget? This study moves beyond conceptual models to provide concrete, empirical evidence on the link between specific HR practices and the psychological contracts employees form with their employers. Surveying over 300 knowledge workers at a major iron ore mining company, the research identifies which contracts—relational, balanced, transitional, or transactional—are most prevalent and, crucially, which HR levers have the greatest impact. The findings are clear: training and development, followed by communication, are the most powerful tools for building the trust and loyalty inherent in relational contracts, while an overemphasis on remuneration may cater only to less committed employees. This research offers a practical, evidence-based model for HR leaders to strategically allocate resources, enhance employee relations, and ultimately boost organizational performance, making it essential reading for any manager looking to justify and optimize their people-focused investments.
