教寫老闆信一問!!!急急急急!!

Your boss is quite reluctant to give you this general confirmation letter without reasonabale ground. It is you to tell the outsider that you are now being employed as a full-time staff in a company unless the other party e.g. bank, finance company etc insist you to produce to them this confirmation letter not only on your employment but your salary as well. This is a specific confirmation letter as required by the other party. So, the letter should be written on each separate event for this specific issue.
A general confirmation letter will be :
This is to confirm that Mr. XYZ is being employed by our company as CE with effect from 1 January, 2008.
