I once worked with a PR pro who had hit a ceiling at work. His CEO wouldn't promote him because of his writing. The CEO was busy, so he never took the time to explain exactly what he meant by that.
And the promotion never appeared.
Don't get the impression that this PR pro wasn't extremely talented. He helped the company grow from a startup to a major player.
But when it came time to have a VP of Communications, the CEO went outside the firm and hired someone over him. He ended up leaving shortly after that.
This happens all the time. PR writing that's just not good enough holds people back.
Bosses are busy people. So what happens when you submit a press release for approval and it's littered with issues?
Sometimes you'll get it back. Sometimes, the boss will just edit the release. Maybe it'll even get rewritten.
But you might never even hear about it.
You also won't get a raise or a promotion.
