When the chorus of the Latvian National Opera decided to strike last year in protest at government austerity measures, the courts swiftly ruled their action illegal.
Fearing a similar reaction, the opera's orchestra hit on a cunning ploy to challenge their 35% pay cut.
Instead of striking, 69 of the 103 musicians yesterday donated blood to the national transfusion service - which under Latvian law entitles them to two days off work. Management attempted to halt the action, claiming the orchestra's recent Russian tour breached a one week quarantine restriction, but in vain. Or vein.
The musicians say they will donate again in nine weeks time if their demands are not met.
