Our school is recognised as Bildungsurlaub by the Federal State of Hamburg (www.weiterbildung-hamburg.de) Based on an agreement of the federal government of 1976, as an employee, you have a right to individual further education. Because education is a part of the federal competence, each state has its own legal regulations.
The language courses must be recognised by the empowered authorities in each state. Mostly, if a language course is recognised in one federal state, it shouldn't be any problem to get recognised by the employees in the other states. Please check this individually with your firm.
In theory, you have a right to 'Bildungsurlaub' after 6 months of working for a company. The duration of the 'Bildungsurlaub' consists of 5 days each year. You can also take 10 days in a period of 2 years.
This is especially recommended for language courses. The employer should be informed by letter in time. He can only reject the 'Bildungsurlaub' based on important entrepreneurial reasons. The 'Bildungsurlaub' cannot be compensated for sick leave. During the 'Bildungsurlaub'you will keep your normal salary.
