Q: What makes a public sector employer different from other employers?
A: Public sector employees are protected by the U.S. Constitution because action taken against them is state action, and thus action under the U.S. Constitution. This is not true for private sector employees.
There are state and federal laws which either do not apply to public sector employers or have different provisions for employers or employees. For this reason, public sector employers should always check to see if a law applies to them or applies differently.
Finally, there are state and federal laws that only apply to public sector employers. At times, these laws may only apply at the state or federal level, and at other times, they apply to all the political subdivisions in the state or under the federal government.
