The Puerto Rico Department of Labor (PRDOL) has issued Guidelines and a sample protocol for employers to follow in complying with Puerto Rico’s prohibition against workplace bullying. The guidelines specifically outline the factors that constitute unlawful workplace bullying. The Guidelines indicate that an isolated event will not satisfy the definition of the statute and thus, will not constitute unlawful bullying. However, the Guidelines also state that employers must investigate any allegations of bullying, even if the allegation identifies only one incident.
