British Citizenship employer's letters confusion

Hi

In 2 month's time, I shall qualify to apply for British Citizenship after living in the UK for 1 year on ILR (ILR was obtained through Tier-2 route). I have a question regarding employer's letters. (I understand that after ILR, there is no employer sponsorship required).

I have come across the following reference in the Guidance AN:
Applications made on the basis of residence in the United Kingdom
If you are unable to provide your passport explain why and supply letters from employers (including start and finish dates), payslips, P60s, educational establishments or other government departments indicating the applicant’s presence in the United Kingdom during the relevant period


I understand that the above statement specifically says, if I am not able to present my passport then I am required to supply the documents listed above. Is there a chance that these documents are required anyway especially "letter from employer (including start and finish dates)". I am just a bit confused because there isn't any document requirement I see other than: Passport, biometric card, Life in the UK cert, English language proof.

The reason I am asking is that I shall be leaving my current employer to join another workplace in a few week's time. Is there a chance that the British citizenship application may somehow ask for "letter confirming my employment dates"? so I can take this letter from my current employer before I leave. Also, would you recommend keeping a letter from work stating my absences from the UK? I have not been outside the UK for more than 450 days in 5 years. Apologies if I am overthinking.

Kind Regards,
Sobs

You don't need an employer letter. You dont even need to be employed. Your are not making an immigration application.
