Hi Employee224,
This must be a bad situation. I don`t know what kind of job you are in. Is it possible to ask him which subjects, things you are doing good? And then what it is he are not satisfied with. Then make a plan with goals he should help you to gain and how he can do that. Then each week have a short meeting where you both talk about what was good and what do you have to work more on? This way he will be more involved in what and how you do the work and maybe he will look at you in another way and see not those things he are not satisfied with, but also those things you are doing good. I am sure if he open his eyes he will also see the good things you are doing...but of course some people are not willing to see the good things..if he is one of them, maybe time to move to another job. Here is an e-book I use in my business, and that is written for business, but you can use the information there in many ways. I think maybe it could help you. It is about different personalities and people can get help to understand their job mates, friends, spouses, etc... read it and see if you can use it for this situation.... http://bodil.successin10steps.com
Wish you all success in your job! And remember it is sometimes better just to find something other to do and get other people to work with.
Maybe you should look if you caould be your own boss?
