The limited understanding from your post is that:
The employee even if on say FTC, is on rolls and is on disposal of employer during work/office hours.
During these hours even if employer has no work, has to pay the employee.The employer might have asked to do some other work.
If the employer wishes to lay off, the lay off compensation is to be paid.
The due notice should have been given.
You may show the contract, all other docs on record, give inputs to an able counsel and let your counsel ascertain the appropriate forum if the matter is not resolved by employer, as per coverage of designation/nature of duties of employee.
