“Brexit has not helped because we had a natural attraction of individuals from the European market who would apply for vacancies in UK airports. We no longer have that talent pool, and we are relying on individuals in the UK,” Mr Sandhu told the BBC.
“It makes it very difficult for recruiters to recruit these individuals because we are all fighting for the same type of candidates.”
Those returning to the UK this week will also face the misery of long queues as Border Force have warned they too have a lack of staff available to check inbound passengers.
Lucy Moreton, the General Secretary of the Immigration Services Union, told the BBC that the agency was struggling with a chronic shortage of officers.
“For the first time in living memory, Border Force isn’t attracting the number of candidates to fill the vacancies they’ve got,” she said.
Ms Moreton warned that this, combined with the particularly large numbers of people travelling over the school holidays, would mean “the queues will move from security based outbound, to Border Force based coming in.”
