I've been with Parasol for a month. My first pay was wrong but I was informed immediately and it was rectified the following week with two weeks free to make up for it. Chris was extremely helpful fixing it despite a 15 minute hold time. They tell me their issues are short-term and unprecedented... I may amend my review if mistakes continue.
Welsh Water engaged with Grant Thornton to assess every contractor individually. Welsh Water then challenged contractors to prove various responses to the GT assessment. A fair, diligent and rigorous approach.
