The atrocities in the French capital have forced companies to reassess how they keep track of employees on business trips, as well as how to contact them quickly in an emergency.

Adam Knights, UK managing director of ATPI, said there had been a “massive shift” in clients’ concerns about the duty of care they provide for their travellers.

“Paris has really focused minds and clients have started to think what if it happens in London? They want to know immediately where their people are if there’s a major incident. This applies to domestic UK travel as well, and we’ve had one leading high street retail client who now wants all rail travel to be booked through us, so they know where their employees are.”

Jason Geall, UK general manager of American Express Global Business Travel, added that there had been an “overnight” change in clients’ priorities following the Paris attacks.

“Paris has sped up the process of thinking about issues such as safety and security, and duty of care – that happened overnight,” he added. “There’s a massive upturn in customers using tracking services where they use data to track managed travellers and communicate with them wherever they are.”

Tracking travellers is also a “major concern” of SMEs, according to Corporate Traveller’s general manager Graeme Milne.

“If you’re not managing your travellers, you have no idea where they are at any time,” he said. “If you have five employees who have booked in five different ways, it’s very difficult trying to round them up and get them home quickly. Traveller tracking is on the agenda for the majority of our clients.”
