I recently joined a company as a software engineer and was told I need to familiarize myself with a development framework to be able to customize a product (via development). I convinced my manager that he needs to increase the time allotted to me (which was a realistic amount from my side after assessing how much time would be needed).
I keep my manager updated usually on what I am doing however recently I was a little unwell at work(just one day) and when he came to ask me for an update (which he usually never does as I am the one pro-actively updating him or asking for more work) , I had a non-work related general news site tab open on my computer at the time which he noticed .
He didn't talk about it and I gave him an update on what I was doing , however it was hard not to notice that I had a non-work related tab open.I did change the tab while I was giving him an update.
I usually am very professional on doing strictly my work in office time (been 2 months since I joined the company), however I am concerned that my manager might now tell me to "speed up my learning", which is something I think is always counter-productive as people need some space and time to learn and absorb stuff when their self-training .
How can I convince my manager (if there is even a need) that I am using the allotted time fairly and professionally? (I don't want one off thing affect my positive image to him).
