In my opinion it is a common pronlem in our current society, because, nowadays, most of the countries which belong to Europe has opened up their fronties. In addition, Spain has inmigration problem from people that coame from different parts of Africa. I believe, that this point is extremely rewarding because we can know about different customs. Moreover we can become better people.
But I can understand to Mr. Shapcott because they are working and it is very important that all the workers can understand each other. Maybe, they must get used to speaking the same language.
On the other hand, in our free time , while we are having lunch, as we see in the Reading, we can speak in the language that we feel comfotdablily. However, the most important thing is respect our collegues, mostly when we are sharing the lunch time so if there are collegues that speak in different language we must use the official language of the company.
