I am an in a QA automation position, with the title "Senior" which is nice. I have a coworker, let's call him Sam, who also has a "Senior" in his title.
I was happy with my title until Sam came along about a year ago; he's not a senior by any stretch of the imagination -- I'd give him a junior title at best. Without going into the specifics, he's lacking the requisite skills to perform the basic functions of the role (without the senior or junior modifier); it's bad enough that I can't even discuss basic concepts with him as he doesn't understand the jargon or motivations and we constantly need to stop to explain the basics. It's not that I believe he couldn't be trained, but he's not there yet.
I know that I can't complain to our lead that I feel the discrepancy in our ability would make Sam a junior -- trying to get someone else's title reduced seems petty; by the same token there isn't really any higher I could rise without changing my role to something different, and I'm not sure I'm ready for that; I'm salty that someone who is unable to perform the work was hired directly to a senior position and needs constant hand-holding.
How can I productively address this issue?
