I have not received a salary adjustment in the past two years.
'Adeguamento' = a-de-gua-MEN-to; four syllables, stress on the third.
Use when a significant amount of time has passed without any pay review, especially if you have taken on more work or if inflation has eroded your real salary.
Referencing the length of time since your last raise is factual and objective. In Italy, inflation ('inflazione') erodes purchasing power significantly. Pointing out that your real salary has declined without an inflationary adjustment is a strong argument.
Il mio stipendio non è stato aggiornato dall'inflazione.
My salary has not been updated in line with inflation.
Economic argument; very effective in periods of high inflation
L'ultima revisione salariale risale a tre anni fa.
The last salary review was three years ago.
States the gap clearly
Da quando sono stato/a promosso/a, il mio stipendio non è cambiato.
Since I was promoted, my salary has not changed.
Specific contrast: new title, same pay
Italian collective labour agreements (CCNL) often include mandatory salary increases tied to inflation indices. However, these sometimes lag reality. Many employees in Italy go years without a real pay rise, especially in the public sector.
