Only a few days ago, Andy Clarke, CEO of Asda, the UK's third-largest grocer by sales, spoke somewhat ominously of "turbulent times" ahead and another tough year with "massive pressure" on supermarket operators. Staff are now learning what exactly he meant by this.According to the UK media, 200 senior management positions were eliminated on Monday with around 600 more still under review. Estimates vary widely, but as many as 1,000 jobs could be at risk at both HQ and store level in a major reassessment that has the potential to affect up to 5,000 staff. This bloodbath follows a cull of 1,360 jobs in the shops last July.But the power to sack provides only fleeting gratification to those in command. Customers begin to complain about a lack of service, and management talent will drift to competitors. Constant fear of redundancy may make employees pleasingly subservient to dominant execs, but it seldom fosters creativity or entrepreneurial spirit.With a motivational flourish that will surely have old Sam Walton, founder of US parent company Walmart, 'a rolling in his grave, the UK media also report that Asda now plans to scrap all canteen facilities along with vending machines and free cups of tea and coffee. What, one wonders, is next?
