For public health reasons, the Government has advised that people should stay at home except in a number of situations, including if they are travelling to and from work where the work is considered to be an essential service. Those essential service providers are listed at: (https://www.gov.ie/en/publication/c9158-essential-services/?referrer=http://www.gov.ie/en/publication/dfeb8f-list-of-essential-service-providers-under-new-public-health-guideline/) and Regulations are in place to support these measures.
The measures are based on expert advice from the National Public Health Emergency Team (NPHET) and are kept under ongoing review by that group, with the over-riding consideration being the protection of public health in the context of the current COVID-19 pandemic.
The Department cannot adjudicate on individual cases. It is a matter for each company/individual to assess, based on the current published information, whether they are involved in providing any of the essential services which are currently permitted.
