The salariés table has a primary key with two columns.

The foreign key reference to salariés has only one column but
the primary key for salariés has two columns, hence the error.
It looks like you should be doing this:

Nom_salarié VARCHAR(20),
rs_ssii VARCHAR(30),
FOREIGN KEY (Nom_salarié, rs_ssii) REFERENCES salariés,
