construction workers such as masons ,carpenters ,steel workers and the likes are not given the necessary respect.

The luxury houses ,offices, the roads and  all other infrastructure that we use were  built by these workers in the construction industry. If you really value the structures built by this class of people then ,you have to respect them and appreciate them .Because without them those facilities you enjoys would not be in an existence. 

show some respect to this artisans.
