Employers are required to keep records of employee remuneration, time worked, overtime, and leave for at least 3 years. Labor officers and designated agents can inspect these records at workplaces and speak with employees about working conditions. If records are missing during a dispute, the employee receives the benefit of doubt. Labor officers have investigative powers to enter premises without notice, check employment records and conditions, and carry out inspections. Corruption such as giving advances to labor officers is discouraged.
