Hundreds of Border Force officers at London's Heathrow Airport are set to strike for four days starting Saturday, causing significant travel disruptions. The industrial action, involving around 650 officers, protests against inflexible work rosters introduced in April, which are claimed to negatively impact the officers' work-life balance and mental health. Following the strike, officers will work to rule and refuse overtime from September 4 to 22. The Home Office has promised measures to minimize disruption and urged passengers to check for travel updates. This unrest coincides with ongoing travel chaos in the UK, marked by frequent delays and cancellations, further exacerbating travel anxiety among passengers. The PCS union and Border Force management are in ongoing discussions to resolve the dispute and improve working conditions.
