Post dated cheque

No quetion of legal or illegal. Whether you are agreeable to the condition or not. What does it mean 1.5 years?

1.5 years mean that I should work atleast for 1year and 6 months for the company.

If I fail to do so then they are entitiled to use the cheque of 1.5lakhs.

I am currently in dilemma that I was scheduled to join from Jan2020, but they are asking for the post dated cheque in oct,2019.

They are doing this,so that I dont join any other company.

If you wish to continue in the job for that contractual period, and if employer gives acknowledgment of having received a cheque there may not be any problem, if the job is good.

You must have a placement assistance cell in the college who have facilitated the Campus recruitment, seek their advice first.If your corse /final exam is over and find the job suitable ,request the recruiting company to allow you to join them from First of Oct.'19.. i.e. from the date of issuance of the cheque. 

Yes, you should bring the mattrs to the notice of the College authorities. Moreover, the cheque, so given, only serves as a security and hence no action under 138 is permissble if the cheque bounces.

if it is a good and established concern, visit the office and enquire the staff placed there for their experience in the similar situation and then decide the matter accordingly. even in adverse the action can be iniated against you for the cheque bounce as the cheque was given for the security purpose

It is already 16th October. Is the offer still open. If you give cheque dated 14th October it cannot be a post dated cheque. Are they asking for an undated cheque or a post-dated cheque? If post-dated what date do they want? In these cases there is no use of fighting. Either you accept or do not accept.the job.

"even in adverse the action can be iniated against you for the cheque bounce as the cheque was given for the security purpose" In my understanding, no action under NI Act is possible if the cheque has been given for purpose of security .
