DC applied for a part-time job at £12ph it was advertised as pay might vary on location, experience and qualification. They have the qualification required. At interview they were told pay was £12ph. When they were offered the job and completed the paperwork the contract came back at £7.90. They queried it but was told it was because they were under 18 and pay would go up to £12ph when they were 18. Can pay be varied by age when it’s not matching National minimum wage levels for those age bands and does their advert need to change? This is a large organisation with 1000’s employers not a small company. Thanks
