What Is The Commitment Expected From A Full-time Employee?

I just was following the discussion on the Employee taking an additional commitment as a consultant...
Made me wonder, what do you expect from a full-time employee? Do you expect him to be 'available' for 24 hours a day? How do you draw the lines between the level of commitment and his personal time? (In short, the work-life balance)
It would be great to see your views...

go through the factory act 1948
thr is written u can take wrok from employee 9 hr a day bt nt exceed more then 48 hr

Thanks Ashish, am not talking contracts and law here... Am a lawyer myself!
Am talking about practice... Do you have overtime in your organization? How do you view personal commitments of employees when there is a conflict with their 'professional commitments'?

Anyone has done a survey on this in their organizations? Or even thought along this dimension...
Would love to see the findings.

I think, this aspect is entirely depends up on the nature of work.
When the nature of work demands full time presense of employees, then the employer offers OT.
Other hand, when OT option is there, employees prefer to encash this opportunity depending up on his family / financial problem.
Regards,

That is interesting... I know that certain organizations have just removed OT, because it causes 'undue' stress to the workforce. Do you agree?
Given your perspective, an employee is the guy playing 'foul', when he is encashing on OT!
After working abroad for several years, especially in countries in Europe, the concept of OT is different. Professionals are expected to be available only for 8 hrs each day. Max 10... People even walk out of 'important' meetings citing reasons like going out for a walk with the wife and children!!!
Where does one draw the line? Some of my clients were not willing to sanction leaves for their subordinates saying that they are indispensable!!! What does one expect from an employee? What does one expect from an employer?
What nature of job is such that a person should be present for 24 hrs???

Is it ultimately an unreasonable commitment made by an employer to someone (could be himself as well!) that drives this kind of a situation?
