It happens, probably once every month, that my manager does not reply to my e-mails where I'm asking a question or just expecting feedback. Most of the time he does reply but the times where he's not still bugs me.
So I work from home some days and sometimes in another office location where my manager is not present. For this reason there are often things I need to coordinate with him, in regards to when I should come to the main office, which tasks I should prioritize etc.
When he doesn't reply, I usually wait around 4-5 hours (that would be half way through the day already) before sending a follow up e-mail. From here there are two outcomes, either he replies in a very short e-mail not answering 1-2 of the questions or he still doesn't reply.
I'm not sure how to deal with this. Do I confront him about it? Am I right to be annoyed by this?
The thing is that when he does reply first time, you can tell that he's in a good mood, answering politely and answers all of the questions. So I'm wondering whether the reason is just that he's really busy or frustrated. But he did tell me himself to make sure to coordinate tasks with him over e-mail.
I kind of feel like I'm being annoying myself, when I send the follow up e-mails
