An orchestra musician’s working week in Germany is counted in Dienste, services. The collective agreement for orchestra musicians, as quoted by the Federal Labor Court in 2003, sets the limit. On average over eight calendar weeks, or 16 in concert orchestras, a musician has to play at most eight services a week. If most performances in that period are of works rated difficult by their score, the limit is seven. A 2008 position paper from the German Stage Association described a regular week as eight services of two and a half or three hours.
