My current supervisor happens to be the owner of the company and, although this person's position and education are nowhere near what we do as a department, this person is still considered our supervisor.
I decided to switch jobs because I don't like how things are done here. There's no protocol; there's no true organization within the department; we have no say nor final word in any matter, although we were hired to make some sort of decisions along the way. Everything must be passed to my supervisor before even considering any changes, no matter how unimportant the topic is (compared to other big decisions or changes) [This person lacks the field knowledge to be making these types of decisions, so we end up with a lot of decisions made up from personal opinions, rather than from a professional perspective].
There's micromanaging and then there's this supervisor's micromanaging. The entire department is annoyed by this, but no one says anything, because the supervisor can't take any type of criticism or comments or suggestions, and gets easily offended (basically everyone is scared of the boss/owner).
There's also the issue that this supervisor needs to know every single detail of our lives (not as gossip but as a way to keep track of us) and questions our decisions of our personal lives, which I dislike a lot.
I've always seen this person as a very good entrepreneur and business person. But the lack of knowledge from the supervisor's part about the things we do in the department cloud my impressions of this person as a team leader. I have a lot of respect for this person but the way things are handled in this particular company are not matching my expectations and make me feel uncomfortable.
The reasons above are pretty rough things to say, not to mention sensitive topics, but these are the reasons I want to leave. My question is, How do I express or bring up these issues without offending this person and without things getting heated up?
