Hello!

With what you are saying in your post, they are taking advantage of you in that company. Hence, I would:

1. Try to negotiate it with your boss, with the same arguments you mentioned. It´s totally legitimate and it should not irritate him what so ever, if you do it properly.
2. If they don´t agree, I would start looking for something else, where I would ensure to negotiate not only the initial salary, but also the 4-year projection the minute you sign.

Whenever you get an outside offer, you can talk again with your boss -you would be surprised of how many times they not only equal it, but raise it, in order for you to stay-.

Best of luck!

Cheers,

Clara

Hello,

How is possible that you signed a contract with no communication regarding your salary?
I think that the best way is to come up with another job offer. It would be fair at that point to discuss about your salary and position in the company.

Hi,
there's nothing strange in discussing with your boss about your salary, and he will be mature enough to appreciate it more than knowing that you left the company even because of the salary. So you can talk about your expectations, your impact in the firm, and your potential opportunity to make a better CV and salary elsewhere. Remember to him how motivated you are with the common goal, but show how he should paying off better the responsibilities you handle.

Best,
Antonello
