The company secretly recruited my position.

This situation is mostly because you think too much. The company's labor cost is not too high. Recruit more people. As long as the final benefit goes up, the salary is a trivial matter. When you come out to mix the workplace, you should always pay attention to your position. Maybe the company just wants to strengthen the department's ability. I don't want you to leave, but your boss may not have talked to you thoroughly. I've been in this situation.
