On the occasion of ADP Day a Guide to internal communications has been published for all production sites and its goal is to improve communication within AD Plastik Group. Good internal communications make us more successful and valuable advices, explanations, examples and tools are supposed to make everyday work easier for employees. For the Croatian language area, a language manual has been prepared in order to raise the level of language culture and to facilitate everyday business communication. In order to preserve our own language and to respect language and social community to which we belong, adequate and linguistically correct business communication is a part of personal and corporate culture. We are all responsible for mutual communication so let’s make it clear and efficient together.
