I've also said nobody's got time to provide suitable home learning resources alongside doing their normal job. Often teachers will be told to send stuff home by management people who know full well that it's largely useless, but who are ticking their own box about having made somebody else do something for long-term absentees.
If I hear from parents asking me for stuff, I'll generally go over and above and send them a proper set of adapted resources together with guidance on how to use them. But the fact of there being a contingent of parents who want an education delivered to their child without making any effort to motivate said child to actually learn, whether at home or in school, that's not up for debate. We see it every day.
