A manager has approached me as they have a colleague who refuses to attend and offer any flexibility around attending school trips because there colleague is breastfeeding. We of course understand that we should do all that we can to support a new parent and don't want to be seen as a poor employer. We do as much as we can to support and aware of HSE requirements. Its become an issue as the employee is refusing to take part in school trips to support the students. I don't have a lot of detail and not talking about day to day work, but they point blank refuse to be flexible. We are not talking weeks away just an afternoon or so. I appreciate that we should offer a breastfeeding area but this isn't possible on a field trip for example, nor taken a child with them. Any thoughts how we can keep the new mum happy and the manager (who is a genuinely kind and supportive and has young children) able to get the support needed for the students. I have read the ACAS advice. This is more about refusal to work.
