Sorry, no: you need to look into the text and application of Art. VI, cl. 3 (the "Oaths Clause") of the U.S. Constitution, as well as the similar provisions in many U.S. state constitutions.

That does NOT apply to "all public employees"

That apples to Elected Officials, Judicial Officers.

Further my state has no such clause in its constitution

> That does NOT apply to "all public employees"

Yes, it does. (Well, arguably not to legislative branch officers who are not themselves legislators, though AFAIK both the federal government and all states actually do have such officers make a similar oath or affirmation to the one required by the Oaths Clause.)

> That apples to Elected Officials, Judicial Officers.

No, it applies to:

(1) All federal and state legislators, (2) All executive officers, and (3) All judicial officers.

"Executive officers" is not the same as "elected officials". The oaths clause use of "officers" has similar breadth of that in the Appointments Clause (Art. II, S. 2, cl. 2) except that the Oaths Clause expressly applies to both state and federal officers, and the Appointments Clause only to federal officers.

> Further my state has no such clause in its constitution

The main additional effect of state oaths clauses (whether Constitutional or statutory) is to require an oath to the state constitution in approximately the same class of state officers that are covered by the federal oaths clause. (They often also reiterate the federal requirement.)
