As you have mentioned, you dont give a damn to your employment,, then iam sure you should not consider this a big risk to sit with you Boss & talk to him in detail...also openly say him what you think of him...& also explain him that anyone will think the same responding to what he acts like..!! Iam sure,,once you are open to him,,you will understand him better & he will know u better too....!!!! just dont be hesitated,think yourslf that you are more intelligent evnthou he is the boss...& have a long conversation on the issue.......

hope this helps...!!! :)
