The cuts were announced earlier this year by the Mayor and Transport for London and have been opposed by opposition AMs and tube unions.
Underground bosses say the changes are needed following a decline in ticket sales due to the success of Oyster and insist that bringing staff from behind the counter will improve passenger experience.
Passenger watchdog London TravelWatch is wants to hear from Tube users about how the proposed changes would affect them so that they can collate the feedback and present it to London Underground.
