I received an offer for a permanent role at a new company for what would effectively be a lateral move from my current position. I'm inclined to accept as it appears to be better for cultural fit and career development.
I understand that both sides takes risks throughout the hiring process, and that throughout a few hours of interviews the new company has assessed my value to be worth X. However I strongly believe that I'm worth at least Y based on: regional market salaries, proficiency, and confidence in the value I will bring.
I intend to try classic negotiations towards that higher salary, however in the event that this fails I'm willing to bet on myself by offering to enter a contract-to-hire period at my target amount Y to prove my perceived value. The idea being: by the end of the period if I met some well defined goals then I'd be considered satisfactory and would continue as normal, otherwise I'd be terminated.
Is this even something that people do? Is this a terrible idea or is it actually viable? Would this help to give more confidence to the employer if the difference between their initial offer and ideal target was 10-20%?
Note: As far as I can tell the company does not offer any true contract-to-hire positions. Most positions are permanent with a handful of temporary
