ATHENS: Transport and services in Greece were disrupted Tuesday for the second time this month as unions staged a 24-hour walkout against government plans to introduce an optional 13-hour workday.

The mobilization will shut down public and municipal services and paralyze ferries and trains, but flights are unaffected.

Urban transport in Athens will also operate on reduced hours.

Protests are scheduled in Athens and other major cities during the day.

The government has said the 13-hour workday, to be voted into law Wednesday, is optional but opposition parties and unions argue that workers will risk layoffs if they refuse longer hours.
