I think scrum, jira, backlogs and always tight deadlines condition people to never sit back and systematically learn something. Instead you feel the urge to always “produce” and feel guilty if you don’t. At least his happened to me. Lately I am making a conscious effort to work from home for a day and take a Udemy class or read a book about something where I feel i don’t have enough background in. The modern frenetic workplace discourages sitting down and systematically learning something.
So as manager take a look and see if your environment makes people into ticket closing machines or into people who have the freedom to allocate their time where they feel it’s most useful.
