Underground strike wreaks London commuter chaos

Millions of commuters struggled to work on Thursday as a strike by London Underground rail staff brought the network to a standstill for the second time in a month over plans for a new nighttime service.

Union workers walked off the job amid a dispute about how to implement a new 24-hour service on weekends. Unions argue work-life balance issues have not been addressed and that management should hire more people to cover extra shifts.

Transport officials say they have offered a salary increase and bonuses to compensate for the changes.
