Can you play Qur'an tapes all the time at work?

Praise be to Allah, the Lord of the Worlds; and may His blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions.

There is no objection to play Qur'an cassettes during work as long as the employer, or the person acting on his behalf accepts that and provided listening to it does not influence the quality or quantity of the work to be performed out. Moreover, the opinion of the workers should be considered, as some of them might not be able to concentrate as long as there is some kind of sound or noise in their area.
Allah knows best.
