However, the union are demanding a bigger increase alongside an improved profit-sharing scheme. BALPA called the pay offer “too little too late,” adding: “It also fails to address the fundamental principle of fairness by denying employees a reasonable share of the success they have helped produce.” In a media statement, BALPA said: “Set against a backdrop of record profits, and despite there being some progress, BA’s offer is too little too late. “It also fails to address the fundamental principle of fairness by denying employees a reasonable share of the success they have helped produce.” A Unite spokesperson told Express.co.uk: “Unite reps will be having further discussions with BA and meeting in the coming days to discuss their next steps. These next steps could include a consultative ballot on any revised pay offer or a ballot for industrial action.” Related articles Flights: Expert reveals THIS is how to get a seat upgrade British Airways shock: Why JFK was 'infuriated' with Concorde plans British Airways: If strike action were to go ahead, it would begin, at the earliest on 5 August (Image: Getty Images) A British Airways spokeswoman told Express.co.uk: "We are extremely disappointed that the pilots' union, BALPA, has raised the prospect of a ballot for industrial action.
