Function not working when inside if or switch statements - oop

Question

I need to solve a OOP problem in which I have to manage multiple classes inherited by each other. First I need to read all the data for all the Employees of a Company. The reading runs very well but I also need to display the read data after reading the command 1 (I need to use switch). I created a function "afisare_angajati()" which only works outside "if" and "switch" statements. I don't know why those statements disable my function. This happened to me before but I couldn't find the cause. Is something that I am not seeing? You can see my function at the end of the code. Thx for help.
#include<iostream>
#include<string>
#include<vector>
class Angajat{

std::string nume;
float salariu_baza;
std::string functie;
float procent_taxe_salariu;
public:
float get_salariu_net(){return 0;}
float get_salariu_brut(){return 0;}
std::string get_nume(){return 0;}
void marire_salariu(){}
Angajat(std::string nume,float salariu_baza,std::string functie,float procent_taxe_salariu=40):
nume(nume),salariu_baza(salariu_baza),functie(functie),procent_taxe_salariu(procent_taxe_salariu){}

std::cout<<functie<<'\n';
}

//pula.afisare_angajati(); output is correct if I put the function outside of brackets
switch(comanda)
