We are frequently contacted by customers thanking our employees in the field for a job well done. It’s tough work, sometimes in very difficult and demanding conditions – especially in winter – so if a job’s gone particularly well for you and a team or an individual has outperformed, we’d love to hear from you. We always make sure our employees and their colleagues know about it.
