In the case of O'Neill v Buckinghamshire County Council the EAT has confirmed that there is no general obligation on employers to carry out a risk assessment for every pregnant employee and that failing to do so does not automatically amount to sex discrimination. The duty is only triggered when three conditions are satisfied: the employee must have notified the employer in writing that she is pregnant; the work must involve a risk of harm or danger to the expectant mother or her baby; and the risk has to arise from working arrangements or from legally specified physical, biological or chemical agents in the workplace. The employee in this case was not exposed to any risk of harm or danger and therefore her claim for pregnancy related sex discrimination failed.
