DH received a job offer with a pay increase and better career progression.
He went to hand in his notice but his current company made a counter offer that offered a slightly higher pay increase and significant promotion. He was asked to decide immediately despite asking for more time. On the surface, it was what he had been working towards for years so he informally said yes and was told to expect a formal offer next week.
For some time he has been trying to negotiate a new role and payrise with current company. Had they made even a small concession, he probably wouldn't have applied for the new job in the first place.
He evaluated both offers fully last night and wants to go with the new job all things considered. Now he needs to tell his current company that he is turning down the counter offer after informally accepting it.
What do you think is the best approach? What would you do?
