Edit: sent it to about 25 folks individually who I worked very closely with (multiple touchpoints a week).
And Before you ask, yes I got their email IDs correct. Maybe they don't want to email me from their company email ID. I sent a few folks linkedin messages/requests but zero on there as well (I know employed people don't log in much)
I know not to expect anything, but it hurts because I thought we had cultivated a bit of friendship on top of our work lives. No well wishes or anything.
Also of the two responses back, one person mainly wanted to keep conversation going so she can ask me questions as she essentially took on a lot of my duties. I'm happy to help her as she's a good person who is stuck in a tough role of replacing essentially 4 people including myself.
Oh well; on the hunt again.
