It doesn't matter if it's a manager or your peers, you shouldn't have to justify your work every single day.
It's childish and immature and if you for some reason need to do it to be able to communicate, learn how to communicate properly, don't foist your miserable way of working on others.
When I tell my team what progress I made yesterday, that's not to justify my existence, it is so they know what has and what hasn't happened. Which is why the among equals, not towards a manager, bit is important.
