In 1998, the ILO adopted the Declaration on Fundamental Principles and Rights at Work (FPRW) that commits Member States to respect and promote: a) freedom of association and the effective recognition of the right to collective bargaining; (b) the elimination of all forms of forced or compulsory labour; (c) the effective abolition of child labour; and (d) the elimination of discrimination in respect of employment and occupation, as these are enshrined in eight ILO conventions (and in the Protocol of 2014 to the Forced Labour Convention of 1930).In June 2022, the International Labour Conference added a safe and healthy working environment as a fifth category. The Declaration makes it clear that these rights are universal, and that all ILO member States, irrespective of their level of economic development, or indeed whether they have ratified the detailed fundamental ILO Conventions, have the obligation, due to their membership of the ILO, to respect and promote this set of principles and rights at work. While there remains a strong international commitment to address violations of these fundamental human rights, decent work is not yet a reality for many people in the world. The ILO estimates that globally 160 million children are engaged in child labour; 79 million of them are performing hazardous work, and that 40 million people are victims of forced labour and other forms of modern slavery, while hundreds of millions of people suffer from discrimination at work. Many workers are not covered by collective bargaining and the rights to organize is often not efficiently protected and, in some cases, even prohibited. Labour inspection plays a fundamental role in the enforcement of labour legislation and is essential for the realization of fundamental principles and rights at work in practice. However, these institutions often face particularly challenging circumstances in carrying out their mandate and functions. Ensuring the protection of vulnerable categories of workers (e.g. underage children, domestic workers and migrant workers just to cite a few), who are especially prone to abuse and exploitation, requires labour inspectors, as well as other law enforcement actors, to take special measures in line with national legislation and international law. Through this four (4) week e-learning course participants will deepen their understanding of how to prevent, identify and act upon violations of FPRW in the workplace. It will also provide them with tools to work around these key issues with more confidence, higher proactivity and efficiency.
