Bit of back history first...My previous job completely knocked my confidence. Iv been with my current company for nearly two years but at my actual store for one year. After 6 months of working shop floor I got promoted to shift leader. Iv recently been having some issues with a colleague so brought it to my managers attention. I asked him if he had any concerns himself about my work and he said nothing serious but a few little things that we'd go over during my yearly review. So now I'm stressing that Iv been doing things wrong. Iv not had a yearly review in any of my jobs but am now really worried. Can anyone offer advise?
