Pilots at Hawaiian and Alaska Airlines are finally set to vote on a combined labor contract, while Nvidia investors got spooked and a massive Microsoft Outlook outage disrupted businesses everywhere.

• Hawaiian and Alaska pilots, represented by the same union, are voting on a joint contract two years in the making, merging seniority lists for 5,600 pilots in one of the most complicated labor deals of its kind.
• Nvidia's stock dropped sharply this week on worries that sales growth could slow without Jensen Huang steering the company; CFO Colette Kress, taking on a bigger leadership role, presents next Tuesday with a huge profit expected.
• Microsoft Outlook went down for everyone, not just individual users, with outages lasting hours and some systems still not working, causing major disruption for businesses that rely on it.
• The Dow is down slightly this morning after a drop yesterday, suggesting a shaky start to trading.

Outlook: Pilots are expected to approve the merged contract soon, Nvidia's earnings next Tuesday will be watched closely for signs of slowing demand, and Microsoft still needs to fully restore Outlook service.
