dear hansa,
As per section 4(3) sub clause (4) no pregnant woman, shall on a request being made by her in this behalf, be required by her employer to do during the period (of one month immediately preceding the period of 6 weeks, before the date of of her expected delivery;) any work which is of arduous nature or which involves long hours of standing, or which in any way is likely to interfere with her pregnancy or the normal development of the foetus, or is likely to cause her miscarriage or otherwise to adversely affect her heath. Violation of this section will attract imprisonment which may extend to one year, or fine extendable upto Rs 5000/- or both. In addition, this will also amount to violation of human rights and appropriate action can be taken thereunder too.
