Pissed, maybe not. Disappointed, probably so.
I get asked to take over something at work when some foreign guy from the "Motherland" country went home that was more responsibility and stuff. Authorities on signing for some important parts of the project. Nothing, just rotate the org chart, not even an email. Never even really a thanks for taking on that steaming pile.
Then, other folks just happen to work in the right spot at the right time and you'd think it was red carpet night or the Academy Awards.
Probably why I hit my workout at lunch. I'd rather feel or show pain on the bike than otherwise.
