OOPNP work letters

[specialmary]

I am preparing work letters for Ontario PNP, but I am confused about its requirements.

Specifically, the letters needed to include job duty descriptions, salary, duration of employment, and 'indication of any extended periods of leave (I.e., more than one month)'. I have already work letters without the extended periods of leave information. Do I need to ask my employers to write again? What should be stated in the letters to show this information about extended period of leave? Any help will be appreciated!
