The Transport for London (TfL) website - which gives passengers information about services and journey times - includes a lengthy attack on a strike by tube drivers planned for Boxing Day.
The publicly funded site does not report the union's side of the story.
Members of the Associated Society of Locomotive Engineers and Firemen (ASLEF) will walk out for 24 hours after talks at the government conciliation service ACAS broke down.
The union is reported to have asked for three extra days' pay and a day off in lieu for its tube members scheduled to work on Boxing Day.
The report on the TfL site refers several times to a "strike called by the leadership of ASLEF".
It doesn't mention the fact that tube drivers voted for industrial action in a secret ballot by a margin of nine to one.
The TfL report says the union signed up to a pay deal which "involved working some public holidays including Boxing day".
ASLEF London district organiser Steve Grant told the Morning Star: "The 1996 agreement covered working some bank holidays - we were then working one in five bank holidays. We are now working all of them, all the time."
