A director asked my colleague, who reports to me, to do some work for her. My colleague then came to me as she was struggling to work it out. I suggested an alternative way of doing it.
Lo and behold I see an email to day from my colleague, to the director, and several other staff, attaching the work and explaining how she had come up with an alternative way of doing it. And getting lots of praise.
She has not acknowledged it was my suggestion. It is not a major piece of work but it just pisses me off a bit. I'm not in the office until next week but am tempted to thank her for getting it done and say I'm glad my suggestion worked. AIBU?
