There are fears of activity at Italy's ports being blocked and chaos in the transport sector due to possible protests and strikes on Friday, when the Green Pass COVID-19 health passport will become obligatory for Italian places of work.
Supply chains could be disrupted due to the new obligation, especially in relation to Trieste, where 40% of the 950 port workers do not have the Green Pass.
Dockers there have threatened to bring the port to a standstill and have said workers at ports in other cities are likely to protest too.
The Green Pass shows that a person is vaccinated for COVID-19, has recovered from it or has tested negative in the last few days.
Alessandro Volk, a representative of the Trieste port workers, has said the dockers would cancel their planned strike if the government postponed making the Green Pass obligatory until the end of the month to allow time to find a solution.
