Etiquette – what is considered to be good behaviour or good manners – is constantly in motion. At the same time, a number of norms and values are in danger of disappearing in our diverse and quickly changing society. There are so many people and so many differences. Dealing with differences can be difficult but we have to if we want to live and work pleasantly together. In addition, it makes you aware of new things and provides new insights. To attain diversity and inclusion, we need etiquette rules.
