Dear Bhusan,
1.the Chief Inspector of Factories, Directorate of Factories is the Final Authority to decide on applicability of the act to your estab. based on his Site Appraisal Committee Registration and Licence will be granted.
2.a probationer will also get all leaves fr which a permanent employee is entitled.
3.difference between cl and el is that
a)cl has to be enjoyed within each calender year and no accumulation beyond that is recorded. Whereas el is accumulated over years and may be encashed at exit time or even yearly, as your company frames the policy. A limit of may accumulation, say upto 300, may be defined..
B) for casual leave avaling prior permission is not necessary and it cant be availed for more than a max 7 days at a stretch, without prefiying, interposing or suffixing sundays or holidays. While fr el prior written permission is to be obtained and grant of it is not right of employee...its management prerogative and discretion, sun/holidays interposed will also count, formal joining report and acceptance of it is must .
thanks & regards
