German unemployment moved back above the four million mark in December, after dipping below in November for the first time in four years.
Some jobs are only available during the summer
According to the Federal Labour Agency, the number out of work rose by 12,000 to 4.008 million. The unemployment rate remained at 9.6%.
But the figures showed a steep drop when adjusted for seasonal factors such as increased summer construction work.
Germany has been seeing better job creation after years of slow growth.
In November, the jobless total in Germany fell below four million for the first time since October 2002.
"The increase in the number of jobless in December 2006 is much lower than usual," the labour agency said in a statement.
And analysts remain positive the recent encouraging trends will continue into 2007.
"The positive outlook for the labour market is reflected by the employment plans of companies, both in the services and manufacturing sector," Alexander Koch at Unicredit said.
The figures came a day after German airline Lufthansa said it would hire 3,000 new staff in 2007, most of them in its home market.
