Today I was contacted by someone at work. She graduated school with me and our 20 year reunion was coming up. Why did she contact me at work? It was the only way they were able to track me down. I was included in promotional material by name. She told me I "was the hardest to track down"and I had to smile.
This is just a small anecdote about privacy practices and their real life impact (and how your employer can undo all of it, I guess)
Luckily I hated everyone in highschool and they never bothered me again once I left. If this has happened to me I’d have laughed in their face.
