That starts off broken and abusing the Scrum process. It's supposed to be "what I completed yesterday" and you move your tasks to done. Then "what I'm working on today" is you move your tasks to in-progress. And you raise any blocking issues that you need help with.

But it always devolves into "what I did..blahblahblah" because both PM/Managers want an accounting and people feel like they need to justify themselves (as you mention).
