The Caribbean Hotel and Tourism Association (CHTA) said an “overwhelming majority” of Caribbean hotels are considering a boycott over Booking.com’s policy to charge commission levied on staff tips.

In a letter to Booking.com, the CHTA cited “a strong negative backlash” from members particularly on how it cuts into employee tips and gratuities.

The CHTA said a survey of its 33 national hotel and tourism federation associations revealed a belief the policy was “regressive and punitive” adding to Booking.com’s revenue while reducing the profitability of the Caribbean tourism industry.
