Is it too soon to leave TT position?
It is unclear to me 'why' you want to give the job more time. Do you expect your workload to decrease? Do you expect your chair to become more reasonable? For academia to change their approach to work/life balance? If the answer to all (or even most) of the questions like this are 'no', then there is no point in waiting. And from my personal experience, the longer you wait in transitioning from academia to industry, the more challenging it is going to be -- and less satisfying.
