I just received a retention bonus which is equal to half my yearly salary, if I stay with the company for 1 year. The thing is it has a clause about revenue synergy and more importantly doesn't pay out until next year. How do I phrase a response to say I'm happy to stay with the company but I want the money now so I can make it work for me and want assurance the revenue synergy doesn't matter? I like the company but also I'm one of the very few experts in my field. Any advice is appreciated.
