A case study of our work: Lancaster University Students' Union

Where we started
Lancaster University Students' Union required a consultant to review their health and safety policies, identifying gaps, and working proactively with senior management on improvement strategies, as well as delivering new initiatives for the function moving forward.

How we helped
Due to the departure of their previous consultant, the Union required a candidate who was able to start immediately. We were able to efficiently provide a shortlist of contractors, with the successful candidate starting the position within 2 weeks. In a short period of time, they have made an incredibly positive impact, working closely with the CEO and senior stakeholders.
