Check and balances is a kind of mechanisms that limit a single individual or body in an institution or government so as to provide a harmonious relationship of the people and all parts of the organisation .
It allows legitimate power to govern and good ideas to be exercised and hence reducing corruption ,abuse of power and oppression .
In employment ensures each entity which is sets with its own powers (balances) and some responsibilities and has to ensure the other entity does not abuse its power(checks)
Thus in employment works run smoothly since there is an oversight from each body
