I work in an organisation of approx 200 people. My emails are often completely ignored by people men even when I have directly asked them (rather than, say, copying them in on something). Part of my job involves raising funds for the company, the people ignoring my emails could positively impact on this at no cost to themselves. (And arguably would benefit from it).
The big boss (female) who I report directly into has previously agreed it is really rude but not really done anything about it except make supportive noises.
I'm utterly fed up. I do a good job but I feel invisible, thwarted and really down.
