In the UK there are a wide range of different religions that both employers and employees may need to have some understanding of and how they may occasionally affect the workplace.
Many workplaces have employees from different religious and non-religious backgrounds. Encouraging greater awareness and understanding of these backgrounds can be rewarding, particularly in terms of team building. It can also help to reduce the chance of misunderstanding resulting in complaints or disciplinary action.
ACAS have produced guidance for employers and employees on how to reduce the chance of religion or belief discrimination happening at work, how it might happen and how it should be dealt with if it does.
