The beard typically indicates that someone is a practising Muslim, they do this in imitation of the Prophets (pbut). In many depictions of Prophets in Semitic traditions they have a beard. 

Some Muslims interpret the following hadith as an obligation, yet the language used does not imply that it is an absolute requirement with a punishment for not complying.  “Cut the moustaches short and leave the beard.” (Bukhari)

Alhamdulillah beards are very fashionable right now so it’s easy for men to grow their beard without being singled out. But if a brother struggles to grow a beard or it is not compatible with his work then there is no blame on him.
