I mean, not quite. My performance at the same level went from high performer to low performer. So I was doing the role very well for a while, even getting good reviews for filling the role above mine (intermediate dev filling tech lead role). Performance gradually atrophied following my disenchantment and mistreatment.
Did you go from high performer to low performer at the same role? what has changed?
Things that changed: subdivisions/teams, tech stacks, managers, areas of the business, enterprise procedures/processes. Basically everything. They even outsourced my job, then laid off my entire old department to ship that entire business unit to another contract company.
Then at home, kids and multiple family health issues. I guess my age plays a role too.
