I am currently with PA, and have an offer from a competitor, which is £12k more than my basic at PA. My bonus this year was £9k (closer to £7k, once you remove the employers NI and the deferred element), so even before any bonus at my new employer, its still a lot more money.I can’t resign at PA until Tuesday April 1st , or I will lose my bonus (two weeks and counting …)I really like the people and the culture at PA, but the pay is well below market norms. Obviously I want to go back to my employers to tell them that I’m moving due to poor pay. My question is, though, do I be open and tell them that I want £12k more, or do I tell them that this is a private matter between me and my new employers, but I’d be open to PA making a revised offer.My aim is to stay at PA, but I’m fed up with being paid so far below the market rate. Which negotiating tactic would be better? Come clean, or let them guess …
