The Health and Safety Executive’s guidance is that employers should provide private and clean facilities (other than toilets) for returning mothers to express breastmilk and a fridge to store it.  

Although there is no legal obligation on employers to do so, a recent case shows that employers who fail to do this could be exposed to sexual harassment claims.

In the case in question, the employment tribunal accepted the failure of provision qualified as sexual harassment because it had the purpose or effect of either violating her dignity or creating an intimidating, hostile, degrading, humiliating or offensive environment for the employee.

RSM, a regular contributor to the NCC’s magazines, has an article on their website about the judgement.
