Depends on the level of effort required for the task in my opinion.

If it's a trivial thing like send an email or some small ask then I wouldn't necessarily expect it to be in writing.

For any non-trivial task I'd expect it to be in writing, even from my manager. Reason for me is that where I work I don't only report to my manager when it comes to how my time is used, but other workstreams and projects, etc.

If I'm busy working on a task for you that is undocumented, then all these other workstreams will wonder what the fuck I'm doing with my time, or may question whether its more important than other tasks. Obviously this is industry specific, since I don't actually work directly with my manager on any projects and probably never will.

From my perspective, my manager has failed or is lazy if they fail to put their non-trivial tasks in writing.
