Factory workers in San Luis Potosí in northern Mexico have been threatened by their bosses with the closure of their factory if they don't renounce their elected independent union in favour of the bosses' union.
The threat from Grupo Modelo in the Industrial Vidriera Potosí factory comes not long after the firing of over 250 workers for being involved with the activities of Sindicato Único de Trabajadores de la Empresa IVP (SUTEIVP).
