The working day begins between 0800 and 0900 and ends at 1700. Many offices shut at 1400 on Friday. Punctuality for both business and social events is extremely important in Germany. The stereotypical north German is hardworking, thorough and fastidious and although such cliches should not be applied too generally, impressive efficiency and firm business sense can be expected from Hanoverian businesspeople. Straight talking is also appreciated.

Both men and women are expected to wear suits - men should also wear a tie. Business contacts must be addressed by their title and surname and using the formal ‘Sie' for ‘you'. Academic and other titles should be used wherever applicable. Visitors to Germany should also note that in some cases, instead of applauding, German businessmen and women may rap their knuckles on the table, although this practice is less common in the north. English will not necessarily be understood, particularly among middle-aged and older people.

Business meetings are usually very formal and kept as brief as possible, while socialising mainly takes place over business lunches, especially on Friday, as many offices close at around 1300 or 1400. After-work drinks are a more casual affair between colleagues and therefore seldom include clients.
