I worked with one such manager who just didn’t like me even when patients and coworkers sung my praises. After trying for a year to just go with the flow I quit! She was flummoxed when I turned in my notice. Sometimes you have to leave for your sanity. I took a large pay cut to be out of that situation and I would do it again!
I think the the first useful skill would be to have patience. Generally, things that are worthy aren’t achieve in a short time, and when it involves other people, needless to say, it is even more so. So have patience and do not expect to resolve the situation with one conversation or one visit to the manager’s office.
What is also helpful, is not to take it personally. It is not an easy thing to do, but as you gain more insight, you realize that things happen because of a multiple, complicated amount of causes and conditions. This approach immediately widens the space out, allowing you to breath and to look at this things with more understanding and increased calmness and strength.
I spoke to their boss and when that didn't help I looked for a new job.
I don't recommend leaving, because horizontal conflict is something you are likely to find everywhere. I think that having the awareness that managers are also people helps. We for our patients without equivocation, but then sometimes forget to extend those same assessments and empathy to those around us. From my observations, being understanding goes further than being defensive. As mentioned prior, try not to take it personally. "Call up" the behavior taking the approach of concern and seeking understanding for why the two of you are having interpersonal conflict. The answers may surprise you. Have a third-party observer and go from there. Many great relationships started in conflict. Best wishes.
Get out now! It took me 7 years to finally leave.
