In today’s world lots of values has changed compared to the past and rules in the job environment are not an exception. In most companies in different nations, employees who own superior positions in administrative charts usually earn more money in comparison with the ones who are new and have less experience.
As we all know, no company would pay extra money on something which does not worth it. Approximately, all workers who engage higher job vacancies are more experienced and it is clear that experience is a direct product of hard effort and studies which both are time and money consuming. That means the experience has not been free of charge for them to earn. Furthermore, workers With higher positions usually spend more time and energy at work. So it seems logical to have higher salaries.
Moreover, when somebody is in a senior position, there is no doubt that he would face different kinds of responsibilities each day which may put him in trouble or make his situation risky. Plus, he is always supposed to monitor and check lower position employees which needs special attention and makes his job more tricky. They also should always be worried about their job security because there is always more demand for higher positions than lowers.
To conclude, at the first sight the difference between salaries might seem unfair, but if we focus on risks and problems which are available in higher positions, At the end we will get to know this difference in salaries is not that much out of justice.
