Sunday-question: Learning Dhamma at working time, on other recource

It might be the case that someone uses to engage into entertaining with Dhamma reads and talks in his working time, or uses resources of other for such, yet not really given, just like one may chat or do whatever private while in the office. What might be the effects of such deeds? Would it be possible to get long term benefit from doing so? Possible to gain good while thinking, acting, like a thief? *[Note that this is not given for trade, exchange, stacks, Buddh-ism or other entertaining that keeps one caught but for liberation.]*
