Salmon farming giant Mowi has been accused of giving workers in its Norwegian homeland massively better terms and conditions than in Scotland.
The Bakers Food and Allied Workers Union (BFAWU), which has seen its membership soar at the Mowi fish processing plant in Rosyth, has accused the company of gross double standards.
A deal in Norway with unions gives staff basic pay equivalent to up to £4 an hour more, protection when sick, generous holidays and flexibility around annual leave.
They also get additional pay for overtime and unsociable hours.In Rosyth, the BFAWU has accused Mowi of refusing to meet or recognise unions.
