Hauliers that play music in staff rooms and public areas are being warned that they may have to pay for licences in order to do so legally.
The Retail Motor Industry Federation (RMIF) has warned its members that several organisations protecting the copyright of musicians are pursuing anybody who plays their music in public.
The RMIF says that not only do many companies not appreciate the regulations, but they are also faced with different organisations that try to enforce copyright.
Sue Robinson, RMIF director, says: "Despite the fact that the law requires businesses that play music in a public area to undertake a licence, there is no single body that enforces the law on the issue. Instead, there are a number of bodies that represent music artists, authors, music producers and musicians."
In addition, some musicians, including the Rolling Stones, issue licences themselves for their own music.
The RMIF is taking legal advice on the matter, but says that anybody not wishing to pay for multiple music licences should not have any music in the workplace.
