No tbh. They seem to like 7pm announcements.
After writing the announcement at 10:30am
I've worked with people like this before, and I'm 99% sure this is what happens:
Step 1: After an announcement, everybody goes home sweating bullets.
Step 2: Next day everybody comes back, things are working "as intended" so you do absolutely nothing for a day.
Step 3: Finally you notice that nobody likes your "intentions" so you decide you need to do something.
Step 4: You spend half a week talking about how to get people to stop complaining while doing as bloody little as possible.
Step 5: After a week of debating you finally get the announcement written and want to release it ASAP.
Step 6: You spend about 12 hours actually completing what you plan to announce, announce it, then leave for home sweating bullets again.
