Medal for the Labour Valour was instituted in one class on April 29, 1895 by the Duke of Anhalt Friedrich I (Leopold Friedrich I Franz Nikolaus von Anhalt, 29.04.1831-24.01.1904) in conjunction with his 64th birthday. The decoration was awarded to male subjects only with at least 25 years of irreproachable continuous service and working record with one employer. Loyalty to sovereign and patriotic spirit were indispensable for pretenders to an award. Those who changed employer or experienced discontinuity of service, with the exception of military service, were deemed not eligible for decoration. Statute of the medal was changed in 1896, when a separate agreement with the Kingdom of Prussia was signed by Anhalt authorities. Since then Prussian subjects who stayed and worked in the Duchy were qualified for decoration with Ehrenzeichen für Treue in der Arbeit.
An obverse had a bust of Friedrich I facing right encircled by his title “Friedrich Herzog von Anhalt” executed in capital letters. Three small five-point stars, the one in the middle being slightly bigger, were situated just below the bust of a ruler.
A reverse bore a central horizontal inscription “For the Labour Valour” (“Für Treue in der Arbeit”) executed in Gothic letters in four lines and encircled by two oak branches tied by a ribbon at its bottom.
Ehrenzeichen für Treue in der Arbeit was worn on the left breast on a silk ribbon replicating national flag of Anhalt, i.e. red, green and white stripes of equal width.
A circular silver medal was 32 mm in diameter and weighed 12,6 g.
Ehrenzeichen für Treue in der Arbeit was awarded in 1895-1918. Totally 7,300 medals were issued within 23 years, 6,490 of which were presented to Anhalt subjects, with the rest being bestowed on Prussians.
