In Italy, nearly all lawyer are self-employed, therefore technically they cannot strike. However, they often refuse to participate to hearings en mass, and judges will simply postpone them.
Italian lawyers’ grievances are various. Trials are too long, something that ironically they are usually blamed for. Prosecutors are too powerful. Jails are too crowded. Fees are too low. And so on.
For example, criminal lawyers will go on “strike” between the 16th and the 20th of September for “the lack of a comprehensive reform of the criminal law as required by the European Union”.
