During meetings or gatherings, which must be done in English, it is very often observed that the interventions of English people block a little exchange. Not because their level is low. On the contrary, the quality of their English often exceeds the understanding of non-English people who often have a rather "globish" English.
The objective of this training is to allow anglés to work a more global English to avoid misunderstandings, or meetings that non-English speakers no longer follow without noticing it so as not to appear ridiculous.
