I love my job and am passionate about it, conscientious etc. I work in a small team of five advisers and two team members give poor and incorrect advice to vulnerable people on a regular basis. I have raised this with my supervisor continually since my last appraisal by email and face to face. A couple of months ago I was accused of being spiteful which upset me and I have tried to voice my concerns in a more constructive way since. I have my annual appraisal coming up and am so angry that the poor advice goes unchallenged and unchecked that I'm worried I'm going to say something I will regret. My question is would any of you as managers be willing to accept an email regarding difficulties with other team members/ colleagues. Would it ever be acceptable to do most of the appraisal on the phone but ask if I can discuss the difficult issues in an email where I know I can be more controlled. Or should I just hope for the best that I can put my points over clearly and professionally ?
