Hadn't heard this - in 2011 the ILO adopted a treaty on global labor standards for domestic workers.
On June 16, 2011, with the world’s attention consumed by street protests in the Middle East and a stubbornly bleak global economy, a quiet revolution took place. Overcoming initial skepticism and resistance, members of the International Labour Organization (ILO)—governments, trade unions, and employers’ associations—voted overwhelmingly in favor of a new groundbreaking treaty that, for the first time, established global labor standards for the estimated 50 to 100 million domestic workers worldwide who clean, cook, and care for children and the elderly in private households.
ILO Convention 189 Concerning Decent Work for Domestic Workers did not topple any dictators, but it does radically change how domestic workers—the vast majority of whom are women and girls—and their work inside the home are valued, recognized, and protected. Its desperately needed and long overdue protections shake deeply entrenched gender discrimination in social and legal norms, and, in some countries, the lingering legacies of slavery.
Governments overwhelmingly voted in favor of the ILO convention, which guarantees domestic workers labor protections equivalent to those of other workers, including for working hours, minimum wage coverage, overtime compensation, daily and weekly rest periods, social security, and maternity leave. The new standards oblige governments to address the minimum age for children in domestic work and their right to attend school, protect domestic workers from violence and abuse, regulate recruitment agencies and fees, and set out measures for effective monitoring and enforcement.
While adoption of the convention was a major victory worthy of celebration, the toughest work lies ahead: ensuring that the convention is ratified, incorporated into domestic laws worldwide, and enforced.[ This essay describes the situation that domestic workers currently face, analyzes how a constellation of forces came together in 2011 to get the ILO convention adopted, and outlines steps that need to be taken now to ensure that this positive development leads to tangible improvements in the lives and working conditions of domestic workers.

I don't know how the ILO goes about trying to enforce such groundbreaking treaties - and that will be hard work - but this is great news. National sovereignty concerns will undoubtedly slow enforcement of these rules which "governments overwhelmingly voted in favor of", but the ILO should push ahead.
