Take a look at this one:
The analysis that I have on this one is pretty simple. Look at the chart and you can only come to one conclusion - broadly, there is no such thing as "pay for performance". For supervisors or normal worker alike. Interesting to see that worker pay spiked post-recession but managers continued to decline. But I digress.
For the most part, employees have to change companies to get a big raise. That remains true.
How much of a raise does it take to steal someone out of your company? That depends how bad your company is or how shitty your managers are, right?
My rules of thumb for how candidates change jobs:
0% increase - candidates only change if they're desperate.
5% increase - you can get average candidates to change jobs for this amount if they're disengaged.
10% increase - where the bidding starts to get a happy productive employee to change jobs.
20% increase - gold standard for what it takes to rip a happy, productive worker out of a company and a job.
Happy hunting out there. Look at the chart and you should be encouraged. On the recruiting side of the house at least - the retention side? That's another story...
