I'm part time in a role that has increased in work load significantly this year.
I have taken on a lot of extra work which has challenged me to breaking limits although I still very much enjoy going to work.
Due to redundancy within management I have taken on even more responsibility and have openly admitted to my director that I don't have time to do what I was initially hired to do although I didn't go into specifics he was happy for me to continue concentrating on the managerial side instead of the non time restricting admin side.
I've dropped a ball, not massively ie financially but it's still a dropped ball and is/will cause others to have to change their plans etc. The manager of the team I dropped the ball for (I'm not answerable to them at all but very much respect them and want them to trust and be confident in me) wants to speak to me about.
From a professional point of view do I tell her I made a mistake and let her know how I plan for it not to happen again (stop doing everyone else's job and just concentrate on mine although I can't do that for another two months) or admit I'm under pressure with too much to do and hope she is understanding?
I can't work full time and tbh if I was doing what I was employed to do alone my role wouldn't warrant full time it's just at this time with the extra support I need to give to others it's making it all very full on.
