Hi Karen
We have been measuring this for a while now as part of our HR dashboard and it was difficult to find a reliable benchmark measure when we started measuring as it varies so much by sector. We are an SME service organisation (both B2B andB2C) with no retail but some hospitality and we aim to keep under 30%. Some retail operations work at 10-12% but the care sector can work at up to 60% so it’s important to consider your business.
Hope that helps, happy to chat further.
Sarah
