My Work Colleague who I work with on a one to one basis everyday keeps telling me she does everything and I do nothing to help her out at work. My Manager is pleased with my work & as far as I know has no issues with me or my work. I do what I have to do as far as my job description goes and work colleague who I work with has slightly more responsibility does her side of the job. She was being very rude to me today about how I do nothing however I did stand up for myself. Should I speak to my Manager tomorrow? Also should I look for another job?
