Dear Mr. Henderson,
Please accept my sincere apologies for the late notice regarding my scheduled commencement date at your firm, which was set for next Monday. Unfortunately, unforeseen personal circumstances have arisen that will prevent me from joining the team as originally planned.
Over the weekend, I experienced a severe flare-up of a chronic back condition, which has rendered me temporarily immobile. My physician has strictly advised complete bed rest and physiotherapy for the next ten days to ensure a full recovery. Consequently, I am unable to commute or perform the physical requirements of the role until my health stabilises.
I have been looking forward to this opportunity immensely and am keen to begin my tenure. Provided my recovery progresses as expected, I am confident that I will be fit to report for duty on Monday, 25th November. I have already reviewed the introductory training materials you provided to ensure I remain up to date.
I regret any disruption this delay may cause to your current projects and appreciate your understanding regarding this health matter. I look forward to your confirmation.
Yours sincerely,
Arthur Pendelton
