Kier Sheffield apprentices past and present were invited to celebrate their experiences over coffee and mince pies.
Some 15 apprentices attended the event, held at the company’s tenant resource centre in Manor Lane, Sheffield, where their efforts were praised by bosses.
Since the creation of Kier Sheffield in 2003, more than 125 young people have completed an apprenticeship with the firm.
In total, Kier has delivered 73,000 hours of training, equating to more than 26,000 training days.
Among workers who have completed apprenticeships is Abu Turay, who arrived in the UK as a refugee from Sierra Leone.
Abu, who lives in the Manor Park area of Sheffield, said: “I faced a lot of challenges when I first came to England, such as learning a new language and learning the culture.
“I would like to say thank you to everyone from Sheffield who has supported me at work and college. Everyone has been very nice to me.”
Nathan Fairfax, aged 20, from Charnock, said: “This apprenticeship has taught me so much about the world of work and construction as a career.
“My mentors at Kier Sheffield have done everything possible to support me and I am proud of what I have already achieved.”
Jordan Dean, 18, added: “My apprenticeship has taught me so much about the world of work. I have been successful in achieving a great deal.”
