I work at a large tech company, and they do mention in the on boarding materials that we represent the company, so we should be careful in our social media profiles. My solution to this is to not associate my social media profiles with my employer. This is technically not really what we’re supposed to do, and I might have to change that approach at some point if I move high enough in the org to start getting attention from people, but this works for me better than disclaimers on all my posts.
