The above question was closed due to being Off Topic. The off topic parts of the question appear to be the use of the word "teacher/advisor" and a comment by the OP stating that she is still in school.
However, the situation itself is very generic. If we substituted the word "manager" for "teacher/advisor" then we have an otherwise common issue that people face when sharing leadership responsibility and dealing with the problems of personality conflicts. Further, in this particular case the OP had to apply for and be "hired" for the job.
My question is: should a question actually be closed simply due to setting (school vs office building) or should questions which are also commonly faced within a traditional workplace setting be on topic?
