According to a recent Gallup poll, 60 percent of Millennials say they are looking for new employment opportunities. This is the largest segment of the working population, and well over half of them are ready to leave their current jobs, should a better opportunity present itself. Because of this attitude, employee turnover is estimated to cost companies around $30 billion annually. This has caused some companies, in a panic, to offer lavish perks to employees in an attempt to build fun places to work, but the gimmicks ultimately ring hollow. According to new research, Millennials’ penchant for job hopping comes down to one thing—trust. Great Place to Work’s study found that building a high-trust culture is the one thing that will keep employees engaged and retained. “You might find some initial benefits to ditching your dress code and throwing out cubicles,” said Chinwe Onyeagoro, president of Great Place to Work. “But superficial changes like these won’t improve retention among Millennials unless they’re accompanied by managers making authentic connections with employees, linking their work and contributions to a broader purpose, providing access to a diverse array of learning and development opportunities, and demonstrating fairness in promotion and advancement decisions. These deeper leadership behaviors and cultural practices affect how Millennials feel about their place in the organization and how long they choose to stay.”
