There is no guarantee of promotion when you come back from gynecological study for one year. The promotion after one year of gynecological study depends on the relevant regulations and policies of your medical institution or company. If organizations or companies need and attach importance to the improvement of professional and technical level, it is possible to improve their skills through further study and promotion. But it also depends on whether your performance and ability meet the requirements of promotion. In addition, it should be noted that one year of gynecological study is only a learning process, and there is no guarantee that you will be promoted. After returning to work, you need to prove your ability and quality through actual work performance in order to get a promotion. Therefore, we should make full use of the opportunity of further study to improve our professional skills, and strive for better promotion opportunities through continuous study, accumulated experience and hard work.
