Hello Shaila,
Like Simhan requested, pl give more details about the overall scenario.
Even though you are a construction company, it will help to gauge the situation IF you can give the size & type of construction activities you carry-out [industrial, residential, commercial, etc, etc].
And presuming you are referring to labor/unskilled manpower when you say 'people', Dinesh is absolutely right when he says "their thought process congealed to such an extent that salary deduction does not matter to them".
Their psyche is absolutely different--they live just for today......in a way, a lopsided implementation of what's mentioned in the Bhagavat Gita ['Live in the Present'].
And they are very used to....irrespective of where they come from.....living with whatever money they have without any complaints--UNLIKE most of us. [Thinking aloud, MAYBE WE have something to learn from them....calibrating our NEEDS to fit-in our resources].
So, in a single line, Policies don't mean anything to them.
Pl give more details IF you wish to have better actionable suggestions from the members.
Rgds,
TS
