Absolutely! Soft skills are always valuable, no matter what role you find yourself in — from entry level to CEO. Being able to understand others, build consensus, break down silos, and manage up? These don’t have tangible ROI, but they’re incredibly valuable to employers as well as to you. They will make everything else in your career go a little more smoothly.
In terms of how, first identify where you want to grow. Is it presentation skills? There are classes for that. Is it understanding others? This can come from books, or courses, or TED talks, but it also comes from experience. Seek opportunities for collaboration with others — particularly those in different departments or with different backgrounds. Your HR department probably knows of some resources for management skills training.
