The FlexScore® is the result of a rigorous 2-step verification of a company’s flexibility

First we assess the flexibility options V7 provides and then we anonymously survey a statistically significant proportion of their employees to make sure V7 is as flexible as they say they are. Our assessment is based on the six key elements of flexibility: location, hours, autonomy, benefits, role modelling and work-life balance.

We ask the hard questions so you don’t have to.
