Dear Boss,
    I have decided to leave my long term employment after 20 wonderful years and would  
 like to take this opportunity to thank you for all your help over this time and hope that  
 the company continues to prosper without me.   
 A change of direction is exactly what I need at this time in my life as is stated in the  
 career opportunity outlined below.     
 Bye Bye…..
