This is so embarrassing, but I'd really love some advice please.
Sorry if this post is unclear in places.
I had a situation today where I had an unexpected phone call from the owner of a place where I volunteer every week.
The owner phoned up to ask why I hadn't done something that I'd been asked to do a couple of days earlier. I said I hadn't done it because another volunteer had stepped into do it and had already done it.
The owner replied that I should have done it because it was my job, not the other volunteer's.
I got a bit teary then instead of asserting myself, and struggled to carry on with the phone call.
To give more context, I have found the owner a bit unreasonable in the past, which may be why I struggled to hold it together today.
I actually would like to give up the volunteering, as I'm finding it a bit stressful because of the owner's attitude, but feel like I have to carry on with it out of politeness and obligation.
Anyway, here's the AIBU:
AIBU to ask you how I can learn to be assertive in challenging situations with colleagues rather than getting upset?
