I currently make $39 per hour but I want to make at least $48.75 per hour because this is one of the few times I can negotiate a raise. The HR at the company has a history of being very difficult in giving raises, but I'm currently working on a contract as a trial period for the company. The psychological challenge is that it's a company that I love so it's easy for my brain to rationalize a lower salary even though I want to make at least $100,000.
I have been with the company for 2 months and the recruiter told me a 3 month trial period, so the time to speak about a full time role is near.
What is the best way to build my strategy of securing this raise? The company is Tony Robbins' main company, aka Robbins Research International.
