Data Protectionists Criticize "Electronic Proof of Income"

Data protectionists criticize "electronic income verification" - and yet another nonsensical data collection action that will only lead to other authorities wanting these data for completely different purposes. What does the state have to do with whether an employee has received warnings or shows "misconduct" (which is then, after all, a matter of interpretation by the employer)? What does the state have to do with whether and how long an employee has gone on strike? The fact that data pools are not secured against misuse should be well known by now. And that any data collection arouses the hunger of other authorities, as well.
