I care a great deal about punctuality.
'Puntualità' = pun-twa-li-TA. Stress the final syllable — it is a stressed noun ending.
Use this proactively in your first meeting or when discussing your work style. In Italian professional culture, punctuality in the workplace (as opposed to social settings) is highly valued.
'Tenere a' means 'to care about' or 'to hold dear'. It is an important Italian idiom. 'Puntualità' is self-evident but saying it explicitly signals professional values.
Sono sempre puntuale agli appuntamenti.
I am always punctual for appointments.
Concrete and verifiable statement
La puntualità è una qualità che valuto molto.
Punctuality is a quality I value greatly.
More reflective; positions you as someone who also expects it from others
Non faccio mai aspettare le persone con cui lavoro.
I never keep the people I work with waiting.
Bold commitment; use only if you are confident you can maintain it
Italy has a cultural split between social and professional time. 'L'ora italiana' (the Italian hour) allows 15-30 minutes of social lateness, but professional lateness — especially for interns — is viewed very negatively and can affect your evaluation.
