Funny, it is always a one way street
If you are the employee you are expected to bend over and take it, normally, without so much as a thank you. But if you dare to ask anything of the company or try to better yourself, then you are deemed to be a traitor. The company can cut you at the drop of a hat, but if you dare to ask anything of them you are a trouble maker.
I would never accept a counter offer. I might ask for a raise, and then go looking if it is not forthcoming.
