Back when they were GTC cards I used to write them all the time.
Mostly because I felt like there were people who backed me up and made my job as a Signing Ninja a little easier every day.
Or they were just great to work with and I was glad they were there.
So many people don't get recognized for the work they do like the HR TM, so I would write him a card just to let him know.
Being a Signing Ninja means you're all over the store and it gives you more chances to do that.
But it's not about, hey you're doing your job so much as , hey I'm glad I'm working with you.
I have to admit I dropped off when they turned into Vibe cards.
Just couldn't get into it the same way.
Petty I know but there you are.
