Simple practices of ensuring workplace efficiency, monitoring and surveillance have advanced leaps and bounds due to technology advances.

The paper compares some best practices from other existing data protection laws and makes suggestions that could be considered for India’s data protection bill and labour reforms to protect workers and their data.
