If you are pregnant, have recently given birth or are breastfeeding, your employer must make sure that the kind of work you do and your working conditions will not put your health or your baby's health at risk. To get the full benefit of this protection you must notify your employer in writing that you are pregnant or have recently given birth or are breastfeeding.
Your employer should carry out a risk assessment of your working conditions and if any working conditions are found to be a risk to your health or your baby your employer must remove or reduce that risk. If the risks remain they must temporarily alter your working conditions or hours of work to remove the risk. If this is not possible your employer must offer you a suitable alternative job. If they can't offer you a suitable alternative job, your employer should suspend you on full pay for as long as is necessary to avoid the risks.
Your employer must also ensure that while at work, you have facilities for resting and expressing your milk (if you want to). All the health and safety conditions apply even if you have given birth to a dead baby.

mental and physical fatigue and other physical burdens
