In an earlier version of this question, I confused the issue by using the word *company* instead of *employer*. Strictly speaking, the magazine is not a company, but I was considered an employee of the magazine, not the publishing house that owned it. I'm not italicizing my other employers. Before I had this job, however, I worked as a freelancer at a variety of magazines, and I list a few examples in italics as part of the description of my stint as a freelancer.
