The past several years I’ve been working at a great company. Interesting work, competent co-workers, reasonable management. Overall, a friendly and fun atmosphere. Only one downside–the pay seemed to be on the low end.
Well, at the beginning of the year, I started fishing for other job prospects. Contacting old colleagues and a few resumes sent here and there. Finally, one bit. I had a couple interviews and they made an offer: similar work and benefits, with a 25% pay increase!
Since I had nothing against my current employer, I gave them a chance to counter-offer. After some friendly negotiation, they counter-offered the same salary increase, plus a little extra. Nothing like an offer-in-hand to show your company what the market value of your job is. 
Yay, me!
