I'm not saying you aren't qualified or that you couldn't handle it, but I'm not sure if that is a discrimination case. Again - NOT saying that you aren't capable personally because I know nothing about your work life or anything like that and for all I know it's a terribly bogus decision - but an anxiety problem that involves being easily overwhelmed or losing your cool or whatever other things like that seems like a somewhat legitimate concern when considering who to promote to management... I mean you can certainly decline to promote someone to management because you don't feel they have the leadership capabilities but if poor leadership ability is labeled an anxiety disorder then it's discrimination?

Obviously I don't know anything about you and how you handle your job or any of that and anxiety issues don't always equate to poor leadership skills - I'm talking more from a theoretical point of view in response to thelostone's comment. I mean if it IS something that is really going to affect your performance I don't know if you can just be like "that's discrimination!".

For example, if I were a paraplegic and worked at the post office sorting mail I wouldn't be outraged because they passed me up for a mail carrier position after working there for 10 years with a great record of attendance/work rate/etc, even if the more junior mail sorters were getting promotions (seeing as walking and driving are primary functions of a mail carrier).
