It makes me so uncomfortable to see staff like this justify the use of these monitoring technologies. Employees are increasingly treating their staff like children, and with headlines like this, it seems increasingly appropriate.
Companies that need keyloggers, often have dysfunctional management and processes to evaluate employees, so need to resort to such desperate measures.
As long as companies don’t use it as some kind of metric then I don’t see an issue. I don’t assume privacy in the office, so why should my work be private?
