According to the Social Security Law, what must employers do regarding employee contributions?

Employers are required by Social Security Law to make contributions to Social Security on behalf of their employees. This means that they must contribute a certain percentage of the employee's earnings, and these contributions are separate from the employee's contributions, which are also typically deducted from their wages.

The correctness of the answer is rooted in the law's stipulations regarding employer responsibilities. Employers cannot deduct any portion of their required contributions from employee wages; instead, they must cover their share in addition to the amounts withheld from employees' paychecks to fulfill their obligations under the Social Security system. This structure ensures that employees' retirement benefits are based on both employee and employer contributions while safeguarding employees from having to pay the entire burden of these taxes themselves.

The other options reflect misunderstandings of employer obligations under Social Security Law. Employers must contribute regardless of the employment type, so contributions are necessary for both full-time and part-time employees. Contributions do not cease simply because an employee requests or because employment has ended; rather, they are required throughout the duration of employment.
