Should I 移动 to another company?

As this has been 未回答的 for 5months i'm very interested to know what 你 have decided on your own terms. Have 你 stuck to your old job 或者 found a new one?
As for your original 问题 there are many aspects that could be why 你 have not been promoted 或者 moved to a different department when 你 have expressed interest. The most positive of these is that 你 are just too good at your job. Many companies see their work as pieces of a clock, when things are working just fine and as it should, they like to leave things as they are.
The other 更多 depressing aspect could be that 你 are just not qualified enough (on paper) 或者 your boss(es) think 你 are just not capapble,
As a very up-front person, i always ask if there are any comments, tips 或者 even some concerns from my employer about my performance every so often. When i started my new job that was monthly, which has now been changed to 6monthly if yearly as i have been with my company for 4years now. That gives my employer a chance to pick up on my best and worst and also gives me insight to what i can improve on.
There is no risk in asking for an assessment, it shows your are serious about your work productivity but 熊 in mind 你 must take what they say seriously and if any areas do need improving take steps to actually improve them .
It could also be worth talking to whoever is in charge of training in your office/department to see if 你 can further your education in the company 或者 learn new skills to give 你 that boost into promotion.
Good Luck.
