What requirement does ERISA bind an employer to?

The correct choice highlights a key component of the Employee Retirement Income Security Act (ERISA), which is primarily focused on ensuring that employer-sponsored retirement plans meet specific minimum standards regarding participation, funding, and management for the benefit of employees. Under ERISA, employers are required to follow certain guidelines that aim to protect the interests of employees in their retirement plans. This includes establishing minimum standards for eligibility, participation, and vesting, ensuring that employers are held accountable for the financial integrity of these plans and that employees have access to their benefits.

In contrast, the other choices do not accurately reflect the requirements set forth by ERISA. While employers may provide health insurance or paid leave, ERISA does not mandate that employers offer these benefits. Similarly, job security is not guaranteed under ERISA, as it primarily pertains to retirement benefits and their administration. Thus, the focus of ERISA on minimum standards for employee participation in retirement plans makes this choice the most accurate representation of the law's requirements.
