This was done with their own rugby events at BT's call centres in Cardiff and Swansea which employ more than 600 people.
As rugby's star players get set for battle in the East v West double derby - colleagues from BT held contests in the East and West with rugby inspired competitions, ticket and merchandise giveaways and their own unique take on a Judgement Day rugby ball throwing contest!
Josh Navidi and Lloyd Williams from Cardiff Blues along with Cory Hill and Tyler Morgan from Newport Gwent Dragons took time out after training on Tuesday afternoon to visit BT's Stadium House centre in Cardiff to chat to BT call centre staff, see the teams at work as well as taking part in a fun rugby quiz and rugby ball throwing competition outside the BT's centre in Park Street, Cardiff next door to Saturday's venue, The Principality Stadium.
Dan Lydiate and Hanno Dirksen from the Ospreys and Gareth Owen and Dylan Evans from the Scarlets visited BT Tower in Swansea for their Judgement Day celebration event with the players having a fun afternoon of rugby events with BT staff.
