You want to change your job after 3 years of hard work without a raise? Want to leave and feel the cost is high? Do you want to change jobs if it is inconsistent with the boss's values?

When you have to fight for decades in the workplace, the probability of encountering a change of boss is not low, so you have to be alert and prepared at all times.
