ITES - Governing Laws

Hi All,
I would like to understand what laws govern the ITES sector around:
Hours of Work (How many hours an employee can be made to work in a day)
Days of Work (How many days can an employee be made to work in a week)
Also, is the ITES sector governed by the Industrial Labor Law, or is there something that has been specifically written for the industry by itself?
I do understand from going through a couple of threads, that the below mentioned labor laws are applicable for the ITES sector, but is there a place I can go to, in order to read through these acts and get a better understanding of them?
1.Shops and Establishments Act
2.Payment of Wages Act
3.Minimum Wages Act
4.Workmen compensation Act
5. Contract Labour Act
6. Employees State Insurance Act
7. Employees Provident Fund Miscellaneous Provisions Act
8. Employment exchanges compulsory notification of Vacancies Act
9. Payment of Gratuity Act
10. Equal remuneration Act
Regards,
Mithran

In addition to the above the Industrial Disputes Act is also applicable to ITES establishments. Also in some states the Industrial Employment (Standing Orders) Act is also made applicable to commercial establishments.
Regarding exemptions, state rules have given some exemptions to IT and ITES companies but the same does not mean that these Acts are not applicable to them. Exemptions like flexible timing, sunday working subject to condition that the employees will get compensatory weekly holiday, exemptions from filing returns etc are available. But there is no exemption from granting of holidays, leaves, ESi, PF etc. As such the employees shall not be called for working for more than 48 hours in a week, there shall be at least one day off every week, the maximum spread over shall not be more than 10 1/2 hours in a day. If the establishment is working only for 5 days a week, it is okay.

Do you also have a link where I can go to in order to get a deeper understanding of these laws along with the exemptions that you are stating about??
