Actually, it will be easier to show any labor law violations with an automated system. Any kind of wrongful termination or bias will be easy to show in the logs.

Note that getting a computer to do something doesn't make it unbiased. People can, and often do, write bias into programs.

Fairer? You mean like Amazons AI recruiting system that was biased against women? You can simply put discrimination into every metric.

And easy to prove when you can show a correlation like the employee being black results in being downrated. Code and especially machine learning systems happily encode our own biases.
