Dignity of labour..
₹espect each and every profession.. But yet government isn't concerned over these labours with their economic needs. Means they aren't paid their wages moths together.
Co-oeprating with Municipal Corporation in cleaning society and treatment of waste materials is every citizens duty. Labour's are not to be addressed with disrespect and not treating them in strange manner . Do respect every job irrespective that it's of your use or not. Some situations do make some to sit and work in a MNC and to some work in scorching sun to walk on their feet with a dust bin carrier to clean and collect the dust and waste so thrown by gentleman and gentlewoman of this society....
Don't laugh at the situation, if possible atleast handle the situation before getting worse.
