This is only true for small sums. No one leaves a job over a 5% raise. Some will jump ship over 20%. But most people absolutely will jump ship for 50% or 200% raises. And, unfortunately for small companies, that's often the wage differential between FAANG and the Small Co.

The numbers you are using here -- 180-250 -- are illustrative; total comp for true Senior at FAANG is comfortably in the 400s.

> The third, deeper, more cynical truth is that posting salary bands probably signals to employees internally that they are being underpaid, and can provoke discontent and departures. Rather than fix the problem with a long-term solution of unilaterally issuing raises internally before posting salary bands, most companies take the shortcut and keep the salary band private.

People talk. They're going to find out eventually. If you're having trouble hiring seniors, ensuring that you retain your existing seniors is probably step zero.
