According to a 2023 Gallup Poll, “68% of employees believe they are overqualified for their current job”. Remember, just because you’ve become bored with a job doesn’t make you overqualified. Doing the same thing day after day can be boring, but it doesn’t make you ready for the next level, necessarily.
So, what can you do to move yourself to the next level / where should you spend your efforts? More training (tons of free online, quality training), mentors at work, and asking for additional responsibility can help you get to that next level in your career. Take ownership of your career to move it forward, don’t expect length of time employed or being bored with your present job as a reason you should be promoted. Your career is worth the additional effort. If your current company can’t see it, move on to another one.
