WiFi SSID, along with the signal strength is used to precisely locate a person down to ~ a meter. Commercial GPS capabilities don't have that level of precision, but when you combined with WiFi information, you can.
You can opinions if you can express them in a more neutral and actionable way.
- My boss doesn't like me and excludes me.
vs
- I think my boss has a few favorites who get all the cool projects. Despite me being the best person as I had the most experience with technology X, my performance in good standing, and having showed interest in the project, I didn't get assigned to that project.
I've made a judgment about the event with what I have read. I have no intention to bully anyone.
My point is clear, we are only reading one side of the story and I don't see an iota of maturity in the story he described. Therefore I also don't believe that his manager called everyone in the town to tell them not to hire him. We don't even know the feedback was sent out to his manager.
Maybe the other employers figured out on their own or maybe they asked his manager for a reference.
Yeah I've managed an assumption based on what I'm seeing here. That's all the data I have.
Similarly most everyone assumed that the manager went out of his way to talk shit about him. Managers don't go around and talk shit of their employees without getting prompted. If someone asks his manager "Hey I saw you worked with aroundtown, what was your experience like" you bet the answer is going to be crystal clear.
Nah man, exit interviews aren't to express opinions or talk shit, it's a data source for HR to identify problems emerging as patterns and improve their org/company.
One guy saying "my boss sucked" isn't really feedback
None of the feedback OP has given to HR has any substance. If you throw around heavy words like this, you better know how to back your words up.
- passive aggressive: This is a personal judgment. He was passive aggressive in what way?
- excluded you from the team: How was he excluded? Was he not invited to events? Or did he not get good projects? If you are a temp with potential performance problems, it's normal that you don't get the cool projects.
- code was awful: Again, is this a sentiment shared by other members of the team or is it just one junior engineer being super opinionated about something
- long term maintainability: I don't think he was there for long
- missing roadmap because poor design decisions: Again a junior opinion, running projects are complex with many different variables, you fail meeting deadlines for various reasons, there's never a single reason, and that reason is never "we had a bad piece of code written by one guy". I don't think OP has the historical context of that led to the that code.
When I hear all this feedback coming from a temp, all I hear is they weren't a team player, they don't know how to be diplomatic and most of the things they are saying are coming out of frustration and have no substance and is not actionable.
It sounds like you weren't meeting the needs of the company either and this is all sour grapes.
If someone is not meeting the expectations or underperforming and it's not a character problem. I'd be open to working with them if they did some growing somewhere else. If however, you have this kind of attitude of blame-shifting and finger pointing without any substance to back it up, no one will want to work with you.
