If you think that Slack requires constant monitoring then I think you are using it wrong. I believe there is zero difference in the reply expectations of Slack and email. As per my initial comment, you are someone who doesn't check email and that's ok, in my engineering manager role I receive over 200 emails a day. Most of these could be 3 - 10 word slack messages but they arrive in my inbox with the same urgency as every other message requiring the same level of triage as a very important contract.

I check (and respond to) e-mails multiple times a day. I said that in the comment you're replying to. Your replies make it clear that you do not have experience at scale. Replying to e-mails in 2-3 hours is not "someone who doesn't check email" and receiving 200+ e-mails where most could "be 3 - 10 work slack messages" is not effective nor efficient leadership.
