Forgive me, but that sounds awful. Does she like this system? Genuinely curious if it works or if it just results in a pushy manager trying to get her numbers up?
Metric-driven automated employee tracking is everywhere. If you're a software engineer or similar at a tech company, be aware that you have a very cushy, unmonitored job by most comparisons.
It isn't "just" Amazon warehouse employees and other low-paid folks.
One thing that most people don't realize at big tech companies is how much your time actually is monitored.
The amount of tickets you close out, the amount of code reviews you publish, how many code reviews of other employees you're doing. There's a lot of metrics that are not openly discussed but are being tracked and watched to make sure you're performing at the same level as your peers.
