Going to be vague as it would be outing.
I got myself into a bit of a situation at work during covid and the lockdowns. I started doing a certain task that wasn't really my role or responsibility. It's a shared task. I did it out of goodwill because work was manic and staff were off sick or isolating so I was trying to be helpful.
Now that things are back to normal I no longer want to keep sole responsibility of this task, it's affecting my other work, but it's likely to cause some pushback from one or two members because it suits them to keep the status quo. Various complicated reasons.
Without asking management to intervene which I do not want to do, it would cause a massive conflict, I need to assert myself that I will still do the task, but not as it has been.
