Dear all

I would like to have clarification on

1. Are any agreement / bond legal in the eyes of law.
2. If so, under which law?
3. If a contract states that an employee is on contractual basis only for 2years and that the contract is renewable after 2years, but employee will be purely a temporary employee, are such condition legal?
4. Again under this agreement if it is written that employee can only leave after giving 2 months notice. Is such condition legal, as on one side the contract states that the employee is on contractual basis only and temporary employment?
5. If against such agreement, company asks for undated cheque amounting 2 months salary and states in the agreement that such cheque will be deposited if any of the condition in the stated agreement is not fullfiled. would like to have a legal opinion on this condition?
6. If a company is permitted towards such kind of agreement, then company can easily walk out by not paying gratuity to the deserving employees.
7. What are the legal implications bonds / agreement?
8. how far employees or labour are safeguarded under such bond or agreement?
9. Certain companies even ask for pay oder deposit which will be released back with 5% interest after 1 year. no deposit slips are given towards it.

I tried to refer the labour law for the above said questions, but couldnt found suitable answer to it. I request you all to help me on this questions.
