My advisor is extremely unhelpful and unprofessional. I don't want to get into the details, but suffice it to say he has 0 interest in what he told me to do, and only rarely shows up for scheduled meetings, maybe 1/4 meetings and even then many hours late. (I came from a job in "the industry" where such behavior is completely unheard of.)
How should I deal with this? If I was still in the industry, I would just go over my advisor's head, and explain what is happening, is this a valid strategy in academia? (I am asking the question in the present tense, but I have already left the program).
Related question: Is such unprofessional behavior common in the academy? I never experienced anything close to this in my undergraduate education.
Following the advice in a comment: I did ask for advice from the graduate committee chair and relayed some issues I had with missed meetings. His advice was more or less "work harder". Well, I think the fact that I complained must have got back to my advisor because he was furious with me the next time we met. Out of the blue he scolded and said something like "I meet with you every time you ask me to." Of course this was completely false but I saw no point in arguing with it as we had plenty of other things to discuss.
