Explanation:

- Workers earn leave based on the days they have worked in a previous year.

- Generally, the leave calculation is 1 day for every 20 days worked.

- For the worker who joined on January 1, 2022, and worked 220 days, including being laid off for 25 days, calculate eligibility: Lay off days generally count as worked days as per some labor laws, bringing total days to 245 (220 + 25).

- Divide 245 by 20 to determine leave days: 245 / 20 = 12.25, which rounds down to 12 days.
