Is this an issue? 3 years as a manager. No promotion. Known that I have young children. Promotions given to a male and females with adult children.

The question is always why are they doing what they are doing (or not doing).  Do you have any evidence that the decisions may be based on your age or gender? if so you might file an age discrimination or gender discrimination claim with the EEOC. It is not illegal to discriminate against women with young children so long as you also discriminate against men with young children. Has your employer ever told you that your children are the reason for their decisions>   Michael A. Caldwell
