I currently receive from my boss projects and tasks with very ambitious deadlines.
At the same time I receive tasks from other sources. For example middle of last week a colleague received a problem to solve. I knew that as I was in cc. It was a very urgent and important problem - every day we didn't solve it, meant that new issues that needed to be solved manually appeared and their manual solving takes a lot of time. The coworker started his vacation on Monday. I had a day off on Friday. So I came to the office on Monday and discovered he didn't solve the problem or even write me an email what he did in this respect. The problem lays in his area of responsibility - I need more time to solve it as I don't have the background knowledge and don't know the people that need to be involved.
So yesterday after spending a whole Monday and Tuesday trying to solve the problem the colleague "left me", I wrote my boss an email (he's travelling) - "Just for your information. We've been experiencing problems with B since middle of last week. [Coworker] left without solving it, so I've been working on that intensively since yesterday". I meant it as a CYA ("cover your ass") - if I'm to work on the issue, I won't have time to deal with "my" projects.
I've received a very harsh reply that I should never escalate such things and that's not the company culture and that we will need to talk about it.
That's not the first time the situation develops like this. However, when I don't say anything, my boss is surprised I didn't do much on "my" projects.
That's why I'm curious if my way of sharing information with my boss is too much. In what situations should information about your tasks be shared with your manager?
Just a few remarks since I have the feeling several people misunderstood my post:
the coworker and I have the same boss
the coworker's task he left me is one that that have serious negative consequences for the whole unit. Everybody knows that the problem needs to be fixed as quickly as possible. That's why boss's criticism wasn't that I took care of that. It was that I "escalated" it.
when I tell my boss other people's lack of action stops me - but I don't take over their tasks, he sends me very harsh responses telling me not to escalate. What's actually the very point of this post. Not the fact that I started to work on that - he did expect me to.
