So this begs the question why we need "stable employment" as a hallmark of the government sector in order to attract talent.

Let's flip the script. How have young people felt about the private sector as their entry level jobs have focused more around a turnover based culture than ever? Do you feel Gen Z is passionate about work or even about trying to maximize their compensation? Do they seem happy or even tolerant of a 9-5 to (not) make ends meet?

What makes you think applying these practices to the public sector will work for the better?

Hard to be passionate about a job that might not be there tomorrow.
