It's better to annonce a closing on a Monday than a Friday.
Employees always worry how changes affect their job security. If they learn about a change of ownership on a Friday, they'll have 3 nights to dwell on it, nervously texting their co-workers throughout the weekend.
If they learn on Monday morning, then you have 5 business days to spend time with them, get them comfortable, and quell concerns. In such situations, 5 days is an eternity, and you can be BFFs by Friday afternoon.
Quell, don't dwell.
