The deaths of more than 30 construction workers on building sites across Europe over the last four months show the urgent need for EU action to raise safety standards in the sector. The spate of fatal accidents involves many cross-border and migrant workers, who are more vulnerable to exploitation through subcontracting, undeclared or illegal work, and bogus self-employment. The number of fatal accidents across construction is increasing across Europe, according to the latest data from Eurostat, however many also go unreported.
