At a job, it's often hard to accept that you're just the latest in a series of employees. This is especially true in the nomadic world of radio. After one of the stations where I'd worked changed formats, I smiled ruefully while listening to the new incarnation. I didn't begrudge the DJ I was hearing, though; after all, she had been let go during a previous format change, enabling me to work there in the first place.
She was the latest in a series, just as I had been.
