Dear Pronoy,
As per the S&E Act, 1954, every worker should get an off for every 48 hours of work. This is mandatory. In your case you have the privelage of availing half day holiday on saturday. Hence your employee leave is counted as one and half day leave only.
The leave is always calculated by prefix and suffix.. For instance, the employee availed leave on the last working day of the week and present himself on the first working day of the week, then his leave is to be considered only on the absent (leave) day.
If the employee fails to present himself on the first working day of the week, then sunday also to be considered as his leave day counting from saturday, sunday and monday....
