> Not if the new guy is 10% better at what they do.
In most cases, this is not the case. In fact, it's often the case that the new person is really new and will require significant hand holding to be productive.
They pay them 10% more because the new person has multiple offers, and most existing employees aren't seeking alternatives, so they have little leverage.
Not if the new guy is 10% better at what they do.
And if he's not, then maybe the others actually deserve that 10% more.
Good thing.
