The problem is that you lack confidence when speaking to your supervisors and managers on the struggles and day to day routine of your job. This leads to you having difficulty in trying to put your points across to make the workplace more efficient and productive. All this is having a negative effect on your prospects of gaining a promotion.
Your main worry is that you will be stuck in a rut and will also be stuck in the same role forever doing the same old routines day in and day out.
