Society in the UK tends to focus on and reinforce individual achievement. This can be compared to countries with a more collective orientation which emphasises the importance of the group's interests over that of the individual. In the UK, the individual and their rights are paramount and generally everyone is expected to look after themselves and their immediate family.
In the workplace, although team work is recognised as an important means to achieving superior performance, individuals within the team may compete and management will look at individual and team performance when conducting individual performance appraisals.
Loyalty to a collective group may exist in terms of religious groupings, corporate allegiances or local community networks and groups, especially amongst national groupings. The extent to which you find this will vary.
