Reskilling & Upskilling: The HR Challenge You Can’t Ignore
In 2025, “reskilling and upskilling” has overtaken almost every other concern in HR circles. A recent survey of UK employers found that 29.3% now call skill gaps their top priority surpassing even recruitment, wellbeing, and retention. This marks a clear shift: organisations are finally recognising that hiring alone won’t solve their capability problems.
Yet the scale of the challenge is settling down. Though some signs point to a slight easing in the overall shortage, demand remains intense in key technical areas, particularly AI, where over half of UK tech leaders warn of serious capability gaps. And in AI specifically, over half of UK tech leaders warn of serious gaps in their teams’ capabilities.
At the same time, nearly 40% of core skills used in today’s jobs are expected to evolve or shift by 2030. The message is clear: businesses need to recruit for today’s needs, but also build for tomorrow. If you are preparing for the skills challenges of tomorrow, we can help you attract and engage the right candidates through smarter, data-driven recruitment advertising.
Why Internal Talent Development Must Lead
Hiring new staff will always play a role, but it’s no longer enough. Many organisations are now leading with internal development: 28% of employers rank upskilling or reskilling current employees as their most favoured tactic against talent shortages. That’s a smarter, more sustainable strategy when hiring costs are rising and external supply is limited.
But the journey is far from easy. Some of the most significant barriers include insufficient resources, lack of alignment between training and business goals, and resistance to change among employees. In fact, fewer companies are investing in formal programmes like apprenticeships, Skills Bootcamps, or technical qualifications than before down from 60% to 54% in the UK. We also support employers adapting to hybrid models by optimising job adverts for visibility across major job boards and professional networks.
To make progress, organisations will need to get smarter about which skills to prioritise. Many are beginning to carve out “future-ready” competencies: adaptability, AI literacy, data fluency, ethics, creativity, and cross-domain thinking. The idea is not just to bridge current gaps but to anticipate what lies ahead. It also means blending flexible learning options like microlearning, on-demand modules, mentoring, stretch assignments, and digital credentials into the fabric of how work is done, rather than limiting training to discrete events. Finally, success requires leadership commitment, continual assessment of impact, and alignment between HR, L&D and business leaders so that investment in skills grows in parallel with strategic goals. By analysing applicant trends across sectors, Serve Talent helps clients identify tightening candidate supply early, allowing them to adjust job marketing and salary positioning before competitors do.
The Risks of Inaction
Allowing skill gaps to persist carries real cost. One estimate puts the annual cost of unfilled skills in the UK at over £6.6 billion, driven by inefficiencies, increased salaries, and reliance on temporary or external hires. Another projection warns that by 2030, up to 20% of the UK workforce could be significantly under skilled for their roles if nothing changes.
In sectors such as AI, finance, clean energy, and manufacturing, skill scarcity threatens growth plans and innovation agendas. Worse still, companies investing in AI without closing internal capability gaps risk leaving those technologies underutilised or even causing misalignment between strategy and delivery.
Final Thoughts
Whether you’re hiring for long-term growth or short-term support, Serve Talent’s recruitment advertising packages make it easier to connect with motivated candidates ready to thrive in modern workplaces. Reskilling and upskilling have moved from “nice to have” to essential. In a landscape where external talent is constrained, the companies that win will be those that build, nurture, and evolve their own people. To do that, you must embed learning into operations, prioritise future-facing skills, and drive alignment among leadership, HR, and strategy.
At Serve Talent, we help organisations not only recruit wisely but also shape workforce strategies that endure. If you are preparing for the skills challenges of tomorrow, we can partner with you to design development programmes, identify gaps, and execute targeted hiring when needed.
