That's useful context if you're weighing this role against a lateral move within the same broad field, rather than against occupations with a completely different pay structure.

Location makes a real difference here: East pays around 57% more than West Midlands for this same occupation, based on the regional breakdown above. If you're able to work remotely or are open to relocating, that gap is often larger than a typical annual pay rise.

What Affects Pay for Plastics Process Operatives, and How to Use This Data When Negotiating

The figures above describe the market, not any one employer's ceiling. A few things generally explain where an individual lands within that range:

• Location: Pay for the same job title can vary by tens of thousands depending on region or state — see the location breakdown on this page for this specific role.
• Experience level: The gap between the 10th and 90th percentile mostly reflects years of experience and seniority within the role, rather than employer generosity alone.
• Employer size and sector: Larger organisations and higher-paying sectors tend to sit above the median for a given role; smaller employers and some non-profit or public-sector employers often sit below it.
• Qualifications and certifications: Professional qualifications relevant to a role can shift where someone lands within the percentile range, particularly in regulated or technical occupations.
• How common the role is: Roles with fewer people employed nationally tend to show wider pay variation than high-volume occupations, simply because the underlying sample is smaller and less standardised.

If you're using this page to prepare for a pay conversation, a few practical steps:

• Bring the actual percentile figures from this page into the conversation — a specific, sourced number ("the median for this role is £X") carries more weight than a general sense that you're underpaid.
• If you have several years of experience or a scarce skill set, anchor to the 75th percentile rather than the median — the median describes the middle of the market, not where an experienced hire should expect to land.
• Use the regional or state figure, not the national one, if your employer benchmarks pay nationally but you're based in a higher-paying area — the location breakdown above is the more relevant number to quote.
• Treat total compensation, not just base salary, as the real comparison — pension contributions, bonus structure and benefits can close a gap that base pay alone doesn't show.
• Time the conversation around a review cycle or a clear recent win, and bring both arguments — the market-rate evidence on this page and your own contribution — together rather than either alone.

Where This Data Comes From

The UK figures on this page come from the Office for National Statistics' Annual Survey of Hours and Earnings (ASHE), the UK government's official annual employer survey of pay — not a self-reported salary site, and not a jobs-board average of advertised (rather than actually paid) salaries. The US figures come from the Bureau of Labor Statistics' Occupational Employment and Wage Statistics (OES) programme, the US equivalent: a large-scale survey of employers rather than job seekers. Both are gross figures — before income tax, National Insurance, or US federal/state tax and FICA — for the reason that gross pay is what's actually comparable across employers and locations; take-home pay depends on each person's own tax situation.

UK occupations are classified under the Standard Occupational Classification (SOC) 2020, and US occupations under the equivalent US SOC system — the two classification systems don't map perfectly onto each other, so where this page shows a UK and a US occupation together, that pairing is our own editorial best match for the closest equivalent role, not an official government cross-reference.
