Not accepting a job offer doesnt.
Walking into your boss office and saying "give payrise of ill leave as i have this offer" then not leaving when you dont get the rise does.
I would also not have staff who are going to drop and jump ship every time they demand a pay rise too. If they deserve one they will get one. Hell i've had ~9% pay rise in the last year due to my performance. But then i deserved it. If you going to sit there and be average, you wont get a payrise for free
