Gratuity Tenure

Dear All,
Tenure for eligibility to get Gratuity is 5 years.
1 year completion equal to 240 days working out of 365 days.
it includes paid Weekly offs, paid Holidays, and approved earned leaves.
1 month equal to 26 days of working.
Formula for calculating gratuity is :
((Basic+DA)*15/26)*Number of completed years.

refer to madras high court judgement[mettur beardshel] its 4 years and 240 days in last year, which makes workers eligible for gratuity, and not only 5 full years..
if u are disabled[partial/permanent] u need not qualify for 5 years rule.same applies on death matters.
it also includes legal strike period, lock out,legal layoff period, which is not due to employee's fault.
In gratuity we consider 26 days for 1 month work...its not that 1 month is having 26 days working period, thats not the logic, in other statues we consider 30 days...
