BERLIN, April 29 (Reuters) - German unemployment rose unexpectedly in April and companies put more staff on shorter working hours in subsidized job protection schemes, data showed on Thursday, in a further pandemic-related setback for a fragile recovery in Europe’s largest economy. The Labour Office said the number of people out of work increased by 9,000 in seasonally adjusted terms to 2.760 million. A Reuters poll had forecast a fall of 10,000. The number of employees put on short-time work schemes increased to 3.27 million in February from 2.9 million in January, the office added. (Reporting by Michael Nienaber, editing by Kirsti Knolle)
