I hope to hell you got points or mileage for your trouble.
I'm glad it worked out, but I'm still gonna bitch-slap you a little, because I do not want you to EVER consider touching your taxable investments to assist your employer again! No, NO, NO!!!
Had I seen this earlier, I'd have said to make some kind of payment to make sure it doesn't show late, which you did, yay. Then I'd have said to let your employer pay any interest charges incurred. Paying interest has no effect on your credit score, per se. It's the high utilization that stings just a bit, but paying off a large balance quickly can also help you get a credit line increase afterward. Then you could start selling trade lines and make some extra cash. You might still want to look into this, especially if you've had this account for a few years.
