Dear Member,
India is a free country and any factory/establishment or any unit may start paying to his/their employees any new type of incentive as part of wages and may call it as puja bonus, attendance bonus or customary bonus etc.etc. The payments of such amounts may differ from industry to industry and place to place. So far as I understand, such type of wages or bonus are nowhere mentioned in the Payment of Bonus Act, 1965.
I request you to please see the provisions of Payment of Bonus Act, 1965 and if you have any doubt or difficulties in your application of such laws, you may mention your doubt by indicating rules/ sections.

Respected Sir
Kindly confirm piece is eligible for bonus or not?
