Employer Letter date validity

[moffat18]

Hello!

I have a few questions about the employment letter.

1. Does the letter need to be dated within one month of the application date? What is the validity period of the letter?

2. Also should that same letter have the work-related absences, or would it be easier for the case worker if it was under a separate letter?

3. I have taken some UNPAID leave - probably totaling 3 working weeks, for each of the 5 year period. Do I need to have my employer include this in the "work-related" absence evidence? The reasons for unpaid leave was either for vacation, getting married, going back to Australia to visit family, birth of child. Do I need to explain this to my employer so they can add it into the letter, which I doubt they would do.

Many thanks!
