From the labour section
>5 For greater certainty, this obligation relates to the establishment by a Party in its statutes, regulations and practices thereunder, of acceptable conditions of work as determined by that Party.
>3. Nothing in this Chapter shall be construed to empower a Party’s authorities to undertake labour law enforcement activities in the territory of another Party.
>6. Areas of cooperation may include:
>(n) addressing the challenges and opportunities of a diverse, multigenerational workforce, including:
>(i) promotion of equality and elimination of discrimination in respect of employment and occupation for migrant workers, or in the areas of age, disability and other characteristics not related to merit or the requirements of employment;
>(ii) promotion of equality of, elimination of discrimination against, and the employment interests of women; and
>(iii) protection of vulnerable workers, including migrant workers, and low- waged, casual or contingent workers;
