Brian Kuller is the head of a construction company in Holby. His company was negatively impacted by the COVID-19 pandemic and left on the brink of bankruptcy.
In June 2021, Rochelle Reigner, an employee of Brian's, collapsed on a construction site due to hypoglycaemia, and Frank Polt left his shift at the site to reunite Rochelle with her infant daughter Isla after finding Isla in a shed that was scheduled to be demolished. Rochelle feared that, because of the company's poor financial state, Brian would not have accommodated a request for flexible hours, but, after Frank apprised Brian of Rochelle's situation, Brian organised a whip-round for Rochelle and assured her that the pandemic meant that they all needed to look out for each other.
