in reply to Certifications are dumb.
Of course, a system like that would be ripe for abuse by the employers, where workers are released routinely before 90 days. That happened in the auto industry, where new workers received a lower status for 90 days, and the employers were not liable for Unemployment Insurance, until that 90 day point was hit. Of course, everyone got let go at 89 days, for some petty reason.
