I am working in IT and I include my supervisor (Technical Lead) in emails whenever needed. I notify him through Jira tickets ( he will get email notification ) whenever something he needs to be aware of about that particular Jira issue. Usually my mails have all the information he needed such as information, attachments, screenshots etc.
Hi sits next to me,and asks me ( most of the time ) like what happened to that issue and expecting me to explain in detail for 5-10 mins at least ( every time ).
I asked him directly couple of times as below.
Did you read my email?
Read my email first and ask me if you need any further information.
But when I say like above he gets upset or angry. So it is counterproductive and bad for my career. On the flip side, if he sends an email, he expects me to act immediately on that email.
How can I ask him to read emails without spoiling my career?
Update: ( after read some answers and comments)
To give more clear picture, He and I are both developers and our roles are 90% the same, so we both get same number of emails/responsibility except as he is from client organization and I am from vendor, I am reporting to him.
He is not managing a big team but only 2 people including me.
