When you’re looking to build your skills for your next career opportunity, it’s tempting to seek out positions at other companies. But it’s often easiest to deepen your expertise within your current organization. After all, you’ve invested time and effort there to build your reputation, earn trust, and establish credibility. You’re also familiar with the culture and probably have more access to opportunities in-house than in the broader industry. So start close to home and seek out special projects or stretch assignments. Ask your manager about options available to you, including any temporary assignments such as taking on new tasks during a colleague’s maternity leave or sabbatical. Look into formal training programs as well, such as technical apprenticeships or outside degree programs that your company will pay for.
