The sectors with the highest numbers of EEA workers in the UK include retail, food services, education, health services and manufacturing of food. Some of the EEA nationals who will be leaving the UK will be medical professionals and teachers who won't be easily replaced, but also workers in hospitality. Critically, the UK has a list of occupations that are categorised as shortage occupations for which the Home Office imposes lighter immigration controls to try and attract migrants from abroad to do these jobs. Medical practitioners, health professionals, nurses, and secondary education teaching professionals have historically always featured prominently on this list. If we don't have the EEA labour force coming in from outside the UK to do such jobs, shortage occupations will be exacerbated.
