I think trust and respect are necessary. I'd start looking for a new place to train.
When we practice Aikido we are trusting our Sensei and fellow students with our bodies in a potentially very hazardous exercise. Trust in the people you are working with is to me very necessary. There is no way I would continue to practice in a place that I did not feel as if the Sensei had the greatest concern for my well being as well as my education.
Respect is important but I have learned it is possible to learn form and take leadership from someone you do not respect or who does not respect you. It isn't the most pleasant situation and not one to be tolerated long term but it is tolerable if you develop the right mental attitude toward what you are doing.
The OP's situation only makes me appreciate the Place I train that much more.
