Assess the situation at work. Analyze the amount of work that you do, how you cope with the tasks and whether competitive employee. If yes, then you have every reason to dialogue with the head of an increase in workload and responsibility. Not necessarily talk about improving the career ladder and an increase in wages. Competent leader reads these moments between the lines. In any case, whatever was in your boss, everyone loves those who are willing to take responsibility and solve complex problems. But time has put everything in its place. But direct dialogue will not be superfluous. On the contrary, it will mark you as a person strong and purposeful.
If you do not have some extraordinary abilities that you can compete with your colleagues, you should not neglect the self-learning and self-development. It all depends on the scope of your activities. But whatever it was, today there are no problems in courses and training in different areas of work. The main thing - to have the desire. And then, after passing several such seminars, maybe you'll realize that's not working in that company, where they wanted. A change of place of work can bring to your life new opportunities and new perspectives. Just do not stand still, and always keep moving forward.
