I wouldn't say I actively seek out training resources for soft skills, but I've been fortunate enough to take a couple of courses where I work. When soft skills such as business writing (emails and communication focus), negotiations (Read 'Getting to Yes' - a very good resource), or other customer service related courses are offered, I will sign up.

It's been a few years since my last soft-skills class, but the information has stayed with me, and continues to shape my communications both with coworkers, managers, and internal customers.

Coming out of college, you tend to think you know everything, and that IT professionals should behave like "Nick Burns, Your Company's Computer Guy" - Jimmy Fallon on SNL. After a few nasty email battles and failed attempts to get results from other software vendors, my manager recommended these soft skills classes, as they became available. The whole world has opened up for me since then, and I have found soft skills to be every bit as important as the IT training that I've received over the years.
