A new survey of senior HR professionals has highlighted concerns about productivity and the ageing workforce.
The research was conducted by Mint Central. Its findings show that 63% of HR professionals said that the biggest threat to workplace productivity in the next five years is an ageing UK workforce - ahead of other issues such as Brexit (21%) or stagnating wages (14%).
Workforce changes are significant, according to the report, because people are living and working longer. By 2022, there will be 700,000 fewer people aged 16 to 49 in the UK, but 3.7 million more people aged between 50 and state pension age.
Iain Bell, managing director of Mint Central, said: "Through financial necessity, increasing numbers of people are working past their retirement age. They have to support elderly parents, children trying to get on the property ladder, paying off their own mortgages, pension short falls and so on."
Meanwhile, millennials are currently the least engaged and least productive segment of the workforce due to short term contracts, low wages and limited roles. Millennials, said Bell, "want stable jobs with genuine prospects for growth and progression and they are more prepared than older employees to leave if this need isn't being fulfilled."
The findings also show that employee apathy and remote working are the main factors influencing the effectiveness of internal communication in the workplace.
Seven in ten (71%) respondents said that online surveys are the most effective technology used to measure staff engagement. Company intranets were ranked as the least effective technology for measuring staff engagement. This is because the UK workforce is increasingly non-desk bound.
When asked about the alternatives to their current employee engagement technologies, 35% of respondents said that an internal communications app would help boost productivity and improve staff morale.
