The job rotation guarantee of Bank of China Hebei Branch is the same as the trial operation of the head office, but most banks will let employees rotate as tellers in the science and technology posts of provincial and municipal branches for a period ranging from six months to two years. Then you need to compete for employment and return to work. But most of them can't go back. Whether you can return to your original post or be promoted after rotation depends on many factors, such as personal performance, company needs, job competition and so on.
