Awareness raising is an important dimension of whistleblower protection, as it can help change the culture and language surrounding whistleblowing, and ultimately break down the barriers and negative connotations associated with disclosing wrongdoing. Nevertheless, almost half of OECD countries do not have awareness raising activities in place. Furthermore countries that provide whistleblower protection through provisions are far less likely to have these types of initiatives than countries with dedicated laws. This chapter examines the various awareness raising activities that have been implemented in OECD countries, and how they can encourage whistleblowing and promote an effective open organisational culture.
