Deutsche Lufthansa AG is facing one of its most intense waves of labor unrest in years, threatening to disrupt its 100th anniversary celebrations and complicating efforts to improve profitability.

The Vereinigung Cockpit pilots’ union called a two-day strike for Monday and Tuesday just as a cabin crew walkout by the UFO union ended last week. UFO then escalated the dispute by declaring further strikes for Wednesday and Thursday, resulting in four consecutive days of walkouts at Europe’s largest carrier.
