Tesco,in my area (South coast) were paying £306 per day about a year ago. Six months ago they wrote to all their locums stating that in the future all the rates would be £262.50 for a week day, and we could decide to accept that or stop working for them. Consequently, I reduced my fees to £250 for about three months. I then asked Tesco to match a better offer from a competitor £300 from a nearby Specsavers. As I was the only locum at the time who could operate their new computer system (which is a nightmare!) they agreed to increase my rate to £300. Sometimes it’s worth challenging rate reductions – especially when they charge as little as £15 for a pair of specs!
