Absence letter

Hi,

I am a bit worried about the absence letter. All my absences were paid but some were taken as time in lieu so my employer would record it as time in the project. Also I know I have not being out of the UK for more than 180 days within the 12 month period and also not over the 5 year period. But I take very short breaks adjoining with the weekends or travel over weekends too.

Anyway my question is, does the letter have to include dates? Or can just say So&so had all his absences approved by the company and paid?

Thank you,

As long as they confirm your absences from work were by their permission
