TLDR version, the job requirement for experience is inconsistent and HR is going with the one that will screw me. And is unwilling to bend.
I don't understand why HR gets to make decisions like these. When you have my director telling the HR director that if he were me, he'd find a different job because of this, and there's nothing else he can do, that's just stupid. Not to mention the fact that apparently HR is screwing two of my coworkers on their raises from similar promotions and won't give them as much as our director wants. It's his freaking budget. Don't get it.
Because your director doesn't know jack shit about how much the jobs are worth in the job market.
If HR let the directors and hiring managers decide salaries, your company would be broke in less than a year. They have no damn clue what they are doing, and most egotistical dipshits think they know how labor markets work and how much they "should" pay their employees. I've seen many smaller companies drive themselves into the ground because they let their directors set wages - either they are too low and they can'[t keep anyone for more than a few months (because the director doesn't "think they should be paid more") or live in the red because they pay way over what they should be. A growing business can hide these problems, but economic blips create colossus disasters.
When you are paid the median for the non-Sr job, you are being compared to others with similar experience and you have the median amount of experience. When you get to the Sr. Title, you (should) be in a different grade being compared to those who have the Sr. job title, thus you no longer have the median experience of a Sr. level position.The typical promotional increase for a ___ to a Sr ___ runs 5-8%.
If you are getting all pissy because you only got a 8% raise for no additional work or responsibility, you should leave the company. HR doesn't want to deal with your shit anyways, you really are not that hard to replace. You'll just become someone else's problem.
EDIT: I work for a company of Physicians that seem to think money grows on trees and would throw money at every person that walked through their door. Every day seems to be a fight with someone who wants to pay some nose-picker who does nothing but hold up a wall for them to make $100k/year because they want to be viewed as nice. If we gave in on half those requests, we would be filing bankrupcy in 5 years, tops. HR is there to keep the company from eating itself alive and to be the bad guy because your boss doesn't want to be viewed as a mean.
Yes, I'm looking for a new job. A Physician took over as CEO is is currently giving into all demands and already took a profitable company and we'll be in the red next couple of years guaranteed.
