Hospital Industry under the ID Act
In my opinion, a hospital is an industry under the ID Act. 99% of the hospitals are commercial.
As per Section 2(ka) of the Act, an industrial establishment or undertaking means an establishment or undertaking in which any industry is carried on.
Definitions in Chapters V-A and V-B
For Chapters V-A and V-B, an establishment means a factory, plantation, and mine. For Chapter V-B, this meaning applies to lay off, retrenchment, closure, transfers, etc. But in V-A, this meaning is limited to lay off only, i.e., for Sections 25A to 25E only. The word used in Chapter V-A for retrenchment, closure, transfers, etc., is an undertaking.
Applicability of Chapter V-B
So Chapter V-B applies only to factories, plantations, and mines employing 100 or more workmen. For an undertaking which is an industry other than a factory, plantation, and mine employing 100 or more workmen, Chapter V-A will be applicable for the purpose of retrenchment, closure, and transfer of undertakings.
Therefore, I believe that for the closure of a hospital, one should follow the provisions of Section 25FFA and Section 25FFF, wherein the word used is an undertaking, not an industrial establishment.
