This is a well written and informative piece.
There are no right or wrongs in this area, but my experience over the years tends to weigh towards the negatives in accepting a counter offer. When a business is faced with a resignation, offering a salary increase or a different job title is often just a knee jerk panic reaction. And from a candidates perspective, surely it's too little too late? Most people aren't going to feel particularly motivated or valued if their resignation is the only way to get a salary increase or promotion. Surely it is far better to value the people that are doing well within the business.
That said, there are bound to be people's resignations that are good news for the business!
Consider the possible repercussions of accepting. Asked to check off as many negative consequences of accepting a counteroffer as apply, nearly 80% of senior executives and 60% of HR leaders cited diminished trust and compromised reputation among the executives and board members of the employee’s current company. Nearly 80% of senior executives and 67% of HR leaders cited the same consequences with the board and executives of the spurned company. And 71% of senior executives and 67% of HR leaders also said that superiors in the current company would question the employee’s loyalty going forward.
