When market conditions give you a glut of "qualified" labor you can afford these practices.
Then again these are precisely the types of "poverty studies" that have been done in India for years. "Should we fine nurses who are late to work? If so, how much?" "Should web publicly shame and harass office workers who leave early? If so, how much?" Lookin' at you, "Poverty Action Lab."
This looks like the logical extension to what we've been putting this country through for years.
