I have joined a bank in March 2018. They offered me something around less than 30k USD per annum. Now I have passed my probationary period successfully, I came to know that range for my position is 80k per annum at a minimum, I am reporting to COO and he was on business trip. i talked with CEO and he told me that come after you completed 6 months of your employment if your line manager COO approved will change your salary but cannot give you the range of this position.
What is your advice?
