Challenging Times Call for Resilience New research by MHR International, the HR, payroll and finance experts, has highlighted the challenges facing mid-size UK and Ireland companies in today’s VUCA (volatile, uncertain, complex and ambiguous) world as they compete with the power of the multinationals and the agility of start-ups. MHR surveyed over 500 senior leaders from businesses employing between 500 and 5000 people to discover how resilience is key to navigating change and challenges. These businesses face similar challenges – three quarters regard stakeholder expectations around growth as a major challenge, while over 70% are concerned about staying ahead of competitive start-ups.
