Dear Dev,
You have asked your query from legal point of view only. In that case I recommend you referring Payment of Wages Act, 1936. I doubt whether your proposal will stand scrutiny of this act.
I would like to go little further and handle this case from management science point of view. When you would like to disclose these conditions of employment to the job candidates? Once these conditions are disclosed, do you think that you will get talented candidates? Will a job candidate who is quite confident of getting job and who has also high level of self-esteem will join under these conditions?
The unsaid part of your post is that your organisation could be facing problem of attrition of newly joined employees. To mitigate the expenses of employee exits, you have tried
pulling this rabbit out of your hat. But then if this policy comes into effect and if some talented job candidate refuses to join, what will be the cost of lost opportunities, have you measured that?
If employees are not sticking then your problem could be with your organisation's culture or your leadership. Please fix either or both the problems. If other companies are able to retain the employees then so you should be. Study your organisation's ills and take remedial measures rather than finding unconventional solutions.
My experience: - I conducted training for the staffs of one major photo studio. They had similar problem. Owner went on to extent of withholding salary for first two months. Even then also attrition did not come down. Those who wanted to leave, they left anyway, without bothering about loss of two month's salary.
Thanks,
