As inflation rises and older workers realize they haven't saved enough for retirement, many are forced to continue earning a paycheck. To make the most out of the last decades of their work life, many older employees are picking up skills in areas such as machine learning, cybersecurity, cloud management and data analytics.Relying on interviews with more than 40,000 employees in 19 countries, Bain's report notes that almost a quarter of those interviewed, 22 percent in the age group 55 to 64, said they need more tech skills. At Coursera, a global online learning platform, Chief Learning Officer Trena Minudri said some older workers possess the steadiness and maturity to stabilize the workplace and to mentor younger colleagues during times of rapid technological change.
