Can notice period during probation period be different? It appears the T & C is biased and one sided

My freind joined in a proprietorship manufacturing firm having two units and employing more than 100 employees and workers. In the appointment letter issued to him it mentions that the company can terminate/discontinue his services giving 24 hours notice whereas if the employee wants to leave the job, requires to give a month's notice. It appears the T & C is biased and one sided. Can someone suggest the validity of this T & C

The title of the thred and the content of the question seem to be at variance.
Notice period for a probationer and a confirmed employee can be different.
But if the notice period mentioned in the post pertains to a confirmed employee, it is certainly biased and cannot stand legal scrutiny in case of any dispute later in this regard.

Probation is akin to "Appointment against a Permanent Position" with the Proviso that Once & after the Performance & Behavious of the Probationar is Found Satisfactory" s/he is confirmed against that Permannet Position. Hence, Notice Period for and in case of Probationer is A Misnomer as Probationers such Provisional Appointment can be Terminated by virtue of Unsatisfactory Performance 7 Behavior and the Probation during his/her Propbationary Period can Quit ifs/he so decided without observing any Any Notice Period, Just Notice so to do shall suffice.

Sirs/Madams,
Thank you for your suggestions.
My query is that my freind is nearing to complete probation in 15 days. If in this period my freind wants to discontinue, 1 month notice period is required as per the clause of the appointment letter whereas if company wants to discontinue his services, then it can do so by giving 24 hours notice. Considering the above biased clauses, can the company terminate him (or a probationer) by giving 24 hours notice and without 1 month's salary compensation??
Further, my freind has not signed the appointment letter and written letter requesting to revise few terms and conditions including notice period. But no reply received from the company so far although 2-3 months passed. Now in the circumstances if company discontinues his services then what would be the compensation my freind can claim? My freind is in a senior position having more than 15 years experience and company has also not written anything unsatisfactory as regard to his performance and conduct.
Please suggest and guide.

With due regard to the view of the learned member from M/S Kritarth Consulting, I have a different perception about the concept of probation in employment and hence I would like to uphold the necessity for a compulsory period of probation immediately following the joining of a new entrant in any organization not only freshers but also experienced candidates. Freshers, despite their brilliant academic records, would certainly need some time to gain practical knowledge and the nuances of their behaviour within the closed social group of employees of the same organization. Thus, it is a predetermined and limited phase or brief duration of time demanding more of orientation to the post held and understanding the work culture of the organization than that of the mere discharge of the mundane responsibilities attached to it. Therefore, it would not be simply appropriate on the part of the employer declaring subjectively in a day or two that the new comer would not fit into the organization and showing the exit nor would it be appropriate on the part of the newcomer to simply walk out the moment he thinks the job is demanding or the work atmosphere is tense.
Coming to the latest query of the questioner, being a senior, his friend would have asked to revise the offer on his lines or simply rejected it instead of joining.
However at this juncture, there are two possibilities in my opinion:
(a)The management may consider the changes solicited and agree at the end of the probation period and confirm him or simply discharge him citing the termination clause in the offer.
OR
(b) May accept the resignation subject to fulfillment of the notice condition in entirety and demand 15 day's salary towards unserved notice period or adjust it in his last month's salary.

Respected Sir,
Thanks for your valuable opinions.
1) The company issued appointment letter to my freind after 2 months of joining following interview. My freind had to join the company without appointment letter as he required a job to manage his households. Some companies have adopted a technique to avoid appointment letters even today's time. My freind or anyone who is looking for an employment can not wait and demand for appointment letter to join as earning is very critical thing.
2) The notice period clauses for employee and employer are not equal ( for employee 1 month to leave and for company 24 hours to terminate). As per my view the clause for the company to terminate an employee should be " giving 24 hours notice with a month's salary compensation". I think purposefully the company kept the clause " a month's salary compensation" silent. Are the notice period clauses during probation period justified?
Hope I have ably written my queries for suggestions.
Thanks.

Dear Colleague,
It is unjust contractual term of notice period being kept different for employee and the organisation.
But having worked for some time now, your friend can continue, or quit by giving one month's notice as it is too late to agitate.

Vinayak Sir,
Many thanks for your suggestions. Further, please share your views of the below:
1) For such like unjust contractual terms for notice period being kept different for employee and organisation, what's the governmental provision to control exploitation and provide justice to working classes at all levels of employment. In today's time, although many Organisations are trying to adopt good HR practices, there are also organisations who are otherwise practicing HR policies. Are there some uniform HR laws to control and deliver social justice to every worker in private sector? Many choose to avoid escalating these issues in their career interest but they suffer financially.
2) In my example, if the company discontinues my friend's services in the last few days of probation period, can my freind ask for a month's salary compensation? Please note that he hasn't given a copy of signed appointment letter as he has written back to the mgt requesting to revise some terms including notice period 2 months back but nothing heard from them ( mgt) till date.
Thanks a lot.

Dear Colleague,
I do not believe such an unjust practice is very rampant in India to cause a concern. On the contrary , in my experience the practice is to maintain equality in the notice period on both sides.
What your friend has been experiencing is rare and right thing would have been not to join any company on such terms in the first place.
I don't see need for governmental intervention as it is not wide practice.

Dear Colleague,
Under any situation either probation period or permanent position, the Notice Period should be same from both sided.
Appointment letter is a kind of contract between the Employer & employee.
Legally this clause of Appointment Letter is not valid.
