What is a common legal consideration in recruitment practices?

The correct answer highlights the significant legal and ethical implications associated with reserving jobs for specific castes. Many countries have laws and regulations that prohibit discrimination in hiring practices based on caste, race, ethnicity, gender, religion, or other protected characteristics. Engaging in recruitment practices that favor certain castes can lead to legal repercussions, including lawsuits and penalties, as it violates the principles of equal employment opportunity.

On the other hand, hiring based on employee referrals, while it can raise issues of diversity and equally important to consider, is generally a common and legally acceptable practice as long as it does not perpetuate discrimination. Offering higher salaries to attract talent is also a standard practice in recruitment, as salary considerations can impact a candidate's decision to accept a position. Providing flexible work hours is increasingly seen as an attractive benefit for employees, but it does not directly relate to legal considerations in recruitment practices.
