Will I (an Ex-pat) working in Italy be able to visit multiple European Countries / Schengen Countries for work on the same VISA on which I will come to Italy?

Hello All,

I am a new member here. My question is as follows;

Question: I am working in India for a multinational company the head quarter of which is in Italy. Now the Italy head quarter has offered me an opportunity to join them as Ex-pat for a period of 2-3 years. They will do all the VISA formality for me. The role they are offering me will demand a lot of travel to European countries / Schengen countries. So the VISA which will be issued to me by Italian consulate in India to go to Italy for work allow me to visit other schengen countries as and when required on the same VISA or every time I will require to obtain a new VISA. For example during my 3 years work contract in Italy if I have to visit Germany, France etc. would I be able to travel with my current working visa or I will need to go to Germany consulate in Milan to again get the VISA for Germany?

Please help me to understand this.
