If you aren't medicated then it is likely to cause issues. If you are medicated but still have problems it can cause issues again. People with depression have similar work difficulties but obviously with bipolar you have the other pole.
Having said that I've been with the same company for over 30 yrs in middle management.
So I believe with some bipolar people there are issues in the work place. I hope that helps.
