The Flight Centre Group subsidiary is facing claims of excessive overtime and underpayment just one week after similar claims were voiced by Flight Centre agents.

The Flight Centre controversy continues, as the embattled FC managing director accuses the ABC of collusion with unions.

Flight Centre boss Graham ‘Skroo’ Turner has asked staff to express their concerns on ABC’s Facebook page, with dozens of employees expressing their support for the company.

An ABC investigation accused the travel giant of “low and confusing” methods of paying agents that have allegedly led to mark-ups of up to thousands of dollars.
