Security guards at Luton airport have launched a lengthy strike in a dispute over shift patterns.
Members of Unite walked out on Wednesday and will remain on strike until July 23 unless talks next week lead to a breakthrough.
The union said the airport was imposing a new shift pattern affecting around 120 security guards which means they will have to work an extra 15 days a year.
Unite regional officer, Jeff Hodge said:
An airport spokesman said: "Previous walkouts by the same small number of Unite members have not caused any disruption and we would like to reassure passengers that it will be no different this time.
