Building team morale through a difficult period — what has worked for you?

We went through a difficult merger last year and morale tanked for about 6 months. What I learned: your team takes its cues from you. If you're visibly stressed and uncommunicative, anxiety cascades down. I started doing brief Friday team briefings — 10 minutes, honest, no clinical content, just 'here's where we are, here's what's coming, thank you for X this week'. It made a real difference. What do others do to maintain culture and morale through disruption?
