"More than anything, hushed-up departures are nearly always a hallmark of management that’s fully disconnected from workers’ day-to-day realities."
This happened to me. I was the glue that held my department together, but it was not always part of my job definition, because our department had been fairly fluid and I was a legacy employee.
Once I was let go, things seemed to fall apart. I even saw a job description 6 months later for my exact position that I, personally, had created over the years, but management didn't realize was important until I was gone.
I mentored and supported new employees who got promoted above me because I was telling them. But there was favoritism, and I wasn't the favorite. Once I was gone, the clothes fell off many employers for how much technological knowledge they lacked.
In my next job, I'm going to just distance myself from coworkers. They never advocated for me when I did for them. When I was let go, they never reached out to me.
Cengage promotes that fake, caring attitude. My direct manager was a prime example: act like she cared until I couldn't be pushed to my limited anymore. But the moment I was let go, no one reached out to me.
