STOP!
Before you reply to this thread, read this!
This thread contains dozens of requsts that say "I need to write a salary increment letter. Please send it to me."
Each time, we have said something like "Write your draft here and we'll help you correct it."
Some people have done so -- they have made an attemp to write the letter and have been given corrections.
If all you are all looking for is a format, then READ THE THREAD and choose your sample. Do not post yet another post saying "send me the sample." If you do, your post will be deleted.
If you have written a draft and need help, then please do post it here, and it will be our pleasure to help you.
