  A suitable closing. 
  It is important to use a closing that is appropriate in the circumstances. 
  If you have a good relationship with your employer, you may want to 
  wish him/her well for the future, and provide contact details that he/she 
  can use to get in touch with you once you have left the organisation. You 
  can then end your letter with a greeting such as “Kind regards,” followed 
  by your signature.
