"The answer lies in the details – in comparing specific provisions of the old laws with their equivalents in the new codes."
For example: "the most consequential change concerns retrenchment – the permanent termination of workers’ employment"... under the IDA 1947, establishments "employing 100 or more workers were required to obtain permission from the central or state government before laying off, retrenching, or closing down operations." Under the new code, "Companies with up to 300 employees can now retrench staff without any approval."
