Dear Mr.Sudhakar,
If the casual labour is a daily or weekly paid employee for a certain quantum of work for a period of less than 240 days in a year, and the contract is also, on the daily or weekly rated of six or five days in a week, the question of weekly holiday payment will not arise as there is no work on weekly holidays.
Secondly for festival holidays also the same.- on humanitarian basis this is given to them, on seeing the regularity of work. This can be allowed, if the casual worker has continuously worked for 2/3 of the working days immediately preceding the festival holiday.
For National Holiday (or) State Holiday, as May Day, it is payable to the casual worker if he is worked for the prefix and suffix days of the concerned national holiday.
But generally getting ,manpower is now very very difficult, hence the employer is simply paying for the national holidays, if he is either worked on prefix or suffix.

V Ganesan
