Dear sirs,

It is with regret that I tender you my resignation from the position of cargo I occupy in this Company. 

The reason I leave the empresa is that I have been offered a better opportunity with another Company which gives me larger scope for my career development. I have much to thank you for your help and guidance during the years I worked under your supervision.

Sincerely,

nome
