The labour ministry warned on Tuesday it would increase inspections of slaughterhouses starting December, to ensure there were no undeclared workers.

If an undeclared worker is found, a €500 fine is issued which is multiplied by seven months, unless the employer can prove the duration of illegal employment was shorter. Should the illegal employment have lasted longer, the fine will be multiplied to reflect that duration.

The inspection department will also carry out checks that basic employment conditions are kept, including wages, hours of work and time off.

The ministry issued a reminder that anonymous, as well as named, complaints and information on labour law violations can be reported via phone at 77778577
