he was ordered to take part in a virtual training period called a "Corrective Action Program." This is the sort of name given to processes uses when an employee is already performing below expectations. (Where I work it’s a more euphemistic Performance Improvement). If that’s the case here then his firing was a bit less sudden than it appears. Though the entire monitoring process seems draconian regardless.
The article also states that he was "telemarketing worker" without much detail about his job duties. Was the company already recording his screen and voice (if applicable) interactions with customers?
> The telemarketing worker replied back two days later, “I don't feel comfortable being monitored for 9 hours a day by a camera. This is an invasion of my privacy and makes me feel really uncomfortable. that's the reason why my camera isn't on. You can already monitor all activities on my laptop and I am sharing my screen.”
