I work with some teams in India and I am ~12 hours offset time wise. I find that they often will often just send “Hi” in Slack. By the time I see that, they are already offline. If I respond with something like “What can I do for you?”, it will be another 12 hours before they see that and then another 12 hours still before I can see whatever request they make. I’ve tried to suggest to some of them that they lead with their request, but that has not helped much.
