Up to 70 jobs will go at Glaxo-SmithKline's Horlicks factory in Slough when the firm outsources carton and bottle production at the end of 2007. "The equipment isn't up to speed with market demand," it said. "Horlicks needs to change its packaging and to install new machinery would be very expensive and require substantial capital." It aimed to relocate some workers to its Maidenhead site.
