Don't Accept a Counteroffer Because....

• Your employer will not forget that you wanted to resign.  In the eyes of your
  employer, you are no longer a loyal employee.  Employees whose loyalty is
  questionable generally don’t get promoted.

• If there are lay-offs to be made in your department, you will be the first on the
  chopping block.

• In the vast majority of cases where people accept counter-offers, they are fired,
  laid off, or looking for a new job within one year.

• Accepting a counteroffer can harm your reputation and character.  Your employer,
  your colleagues, and those who hear about your acceptance of a counter-offer may believe that you can be bought.

• Your company probably has a schedule to which they adhere when raising an employee’s wages.  The extra money given in your counter-offer may simply be an
  early advance on your next raise.

• Your company may only keep you until they find a new employee who will do your
  job for less.

• Unless your decision to resign was salary-based, the same issues that bothered
  you in the first place will probably come up again.  Remember why you initially
  decided to resign.

• You may lose the respect and acceptance of your colleagues when they hear that
  you threatened to resign.

• If your employers are offering you more money, did they not value you enough sufficiently beforehand to have given you a pay increase?

• If you’ve handed in your resignation, you’ve already accepted an offer from another employer.  By accepting a counteroffer, you are breaking your word to your new employer, and that doesn’t bode well for future relations with that company.
