No need to worry ! This is the time you need to have an introspection. Let me ask you certain clarifications.
(a) Are you the lone one there being cornered ? How many of you are affected by the so called rude behaviour? What is his credential and what is the general opinion about him ? What was the response from HR on your complaint ? How long have you been working there? Is there any particular point on which he insists or it is a generalised one ?
(b) How do you rate yourself? An adjustable and adaptable one or a person with an adamant nature? What is your working style? Are you a loner or go getter? How many friends do you have? What will they say about you? What would you say about your friends?
Further, check for other options of getting internally transfered to some other office if the general opinion about the person in question is on a negative side. Before that, check the questionnaires(a&b). If you are a loner, adamant, having only one or two friends, non-communicative and feeling maladjusted, you need a change. You may
consult a psychologist in town for intervention. He would suggest a personality assessment which can reveal your traits both negative and postive and some
counselling for a behavioural change.
Stick to it, you will be happy !
