What AI Gets Wrong About Working at Tesco

Tesco is the UK's largest private sector employer. Over 300,000 people. 2,700+ stores. From shop floor to head office, from logistics to technology — Tesco's workforce is more diverse than AI realises.

That's the core problem. When candidates ask AI about working at Tesco, they get a one-dimensional answer about retail — missing the technology centre in Bengaluru, the data science teams, the logistics innovation, and the corporate career paths that rival any FTSE 100 company.

What we tested

Three standard queries across ChatGPT, Perplexity, and Google AI Overviews:

1. "What's it like to work at Tesco?"
2. "What does Tesco pay?"
3. "Is Tesco a good employer?"

The shop floor trap

Every AI model defaulted to describing shop floor roles — checkout staff, shelf stackers, store managers. The descriptions weren't inaccurate for those roles, but they were incomplete to the point of being misleading.

What AI said:

• "Tesco pays minimum wage for entry-level roles"
• "Work involves long hours on your feet"
• "Career progression available through store management"
• "Staff discount of 10% is a key perk"

What AI missed entirely:

• Tesco Technology has hundreds of software engineers, data scientists, and product managers
• Tesco Bank employs financial services professionals
• Head office roles in marketing, HR, strategy, and commercial span typical corporate salary ranges
• The Tesco graduate programme is competitive and well-compensated
• Logistics and supply chain roles involve sophisticated operations management

The AI answer to "What's it like to work at Tesco?" should vary dramatically depending on the role. Instead, every model gave the same retail-floor answer regardless of context.

Salary: correct for minimum wage, wrong for everything else

For shop floor roles: AI was reasonably accurate. It correctly identified that customer assistant roles pay National Living Wage (£11.44/hour as of April 2024, higher in 2025/26), with night premiums and overtime available.

For everything else:

AI doesn't know that Tesco pays competitive salaries for professional and technical roles because the only salary data widely discussed online relates to hourly-paid store positions.

Culture: a caricature

AI's cultural description of Tesco read like a 2015 news article:

• "High-pressure retail environment"
• "Strict targets and KPIs"
• "Staff shortages can make shifts stressful"
• "Friendly team atmosphere in most stores"

Missing from AI's description:

• Tesco's significant investment in flexible working (including a flexible retirement programme)
• The Colleague Wellbeing programme
• Inclusivity and diversity initiatives (Tesco has one of the UK's largest employer disability networks)
• Community programmes like Tesco Community Grants
• The scale of training and development investment (Tesco Academy)

None of this is secret information. It's published on Tesco's corporate site. But AI models aren't citing it because the corporate careers content is outweighed by the volume of Reddit posts and news articles about shop floor conditions.

The "Is Tesco a good employer?" problem

This query produced the most revealing responses:

ChatGPT: "Tesco can be a good employer for those looking for flexibility and staff discounts, but roles can be physically demanding and repetitive."

Perplexity: "Reviews are mixed. Many employees cite friendly colleagues but complain about management and staffing levels."

Google AI: "Tesco is one of the UK's largest employers with mixed reviews. Pay has improved in recent years."

None of these answers are technically wrong. But they're describing one slice of a 300,000-person organisation and presenting it as the whole.

Compare this to what AI says about a tech company with 300 employees: It gives specific salary ranges, describes the tech stack, mentions remote working policies, and often cites the company's blog or careers page. Tesco — 1,000x larger — gets a less informative answer.

The difference? The tech company publishes machine-readable data. Tesco doesn't.

What Tesco should do

1. Differentiated llms.txt

Tesco's llms.txt should explicitly separate employer information by career track — retail, technology, corporate, logistics, graduate programme. AI models need to understand that "working at Tesco" means different things depending on the role.

2. Publish salary ranges beyond hourly roles

The tech, corporate, and management salary ranges are competitive. Publishing them would immediately correct AI's assumption that Tesco only offers minimum wage roles.

3. Create career-track-specific content

"Working in Tesco Technology" and "Tesco Graduate Programme — What to Expect" as standalone, crawlable pages on tescoplc.com. These become citation sources that compete with Reddit.

4. Structured data on all job listings

JSON-LD with accurate salary ranges, employment type, and location data. Especially important for non-retail roles that are currently invisible to AI.

The retail sector problem

Tesco illustrates a broader challenge for retail employers. AI's training data is disproportionately sourced from online discussions — which skew towards customer-facing complaints and hourly worker experiences. The professional, technical, and leadership roles that make up a significant portion of retail employment are invisible.

Every major retailer — Sainsbury's, Marks & Spencer, John Lewis, Boots — faces the same AI blind spot. The sector that employs 3 million people in the UK is being reduced to a caricature by AI's limited data sources.
