Tech employees are losing out on resources to assist their continued success. These resources can be material, but also, in the case of mentors, they can provide career guidance and advocate for promotions.
And if those numbers aren't daunting enough . . .
The moral of the story is that employees don't want to be stuck in one position. The only way to keep them engaged is to ensure that they have the support they need to do great work and grow in their position. If employees aren't finding this kind of support available in their workplace, it comes as no surprise that they might consider finding another employer.
Offer a mentorship program at work where more-tenured employees can volunteer to guide the younger or less-experienced employees. And when new hires come on board, make sure they have an assigned mentor to guide them through the first few weeks on the job. This will not only help build bridges within your organization and team, but it will also make sure new hires are onboarded quickly and efficiently.
