Easier solution….layoff all those sycophants who “reply all” to Emails. And if the original Email requested recipients to not “reply all” to an Email, as it was sent to a large distribution list, then they should be sacked for being incredibly stupid sycophants and not receive any pay out.
That should wipe out a good truly useless 10% of headcount. If they need more volunteers for LR then start adding those Spark Spammers too. Productivity would improve instantly.
