Budget cutting will cost 126 security screeners at Lambert Field in St. Louis their jobs. The federal Transportation Security Administration announced this week it planned to layoff 3,000 screeners across the country by the end of this month and another 3,000 by the end of September. Screeners at Lambert are among those being given the axe. Lambert currently employs 628 screeners. An official with the Transportation Security Administration says the agency would make the most of its smaller work force by coordinating screener shifts with airline schedules, using part-time employees during peak periods, and by installing more bomb-detection machines.
