Posted By Chris Pope If I were an employer I would like to be considerate to you and try to avoid sending you into premises where access is likely to be difficult. I can't see any good reason for delaying telling the employer. If the employer is unlikely to take a balanced view on this very normal employment issue start looking for another employer.

Posted By David Curless Your employer is obliged to carry out risk assessments specific to your pregnancy and work role/taks. If he does not know, then he obviously cannot do this.

Posted By Roger the Dodger If you have an accident and your pregnancy was a factor in it, having NOT told your employer they would have a sronewall defence against you. Your employer has no additional responsibilities towards your or your baby until you have formally told them with a confirmation note/certificate from your doctor/midwife. You should inform tham as soon as you reasonably can. As said before, if your employer has an issue with your pregnancy, its time to get another employer - its 2005 not 1925.

Posted By Mark Talbot Congratulations! There is no legal duty to inform by a specific date, but there is a legal duty to inform the employer of anything that would compromise your safety - or those of others [e.g. your baby]. So, an informed approach after talking with health professionals would be the best option. I don't know your reasons for delaying the announcement, but they should be weighed against the benefits of an informed employer. Asebestos is not going to be the problem to your baby, but as Linda said, the working conditions might put undue stresses on your, and baby's, body. Good luck ... Mark
