I thought it was OK - Check-out Assistant Tesco Employee Review

Despite being the UK's largest private employer, I felt like a valued employee. I felt as if common sense prevailed - which is an unusual thing in a lot of companies. If you wanted time off then you could apply (it was often granted) and if not, they were more than happy for you to swap a shift for a colleague who needed some extra hours. Other benefits included: Christmas bonus, nice staff areas with discount food, always paid promptly and often completed feedback forms.
