The Invisible Cost of the Summer Campaign: What Happens Between Day One and the First Productive Shift
Every summer, Spain's service sector goes into mass recruitment mode. Hotels, restaurants, retail chains, and tour operators race to fill positions before peak season hits. And every year, success is measured by the same metric: contracts signed.
But there's a question almost nobody asks: what happens after signing?
Because between a new hire's first day and the moment they can actually serve a customer without supervision, there's an operational gap. A gap that costs money. Money that doesn't show up as a line item in any budget, but hits campaign margins all the same.
That space between "hired" and "productive" is what this article is about. And if you manage operations or lead the people function in a service company, you probably already feel it — even if you've never been able to put a number on it.
According to Randstad, Spain's 2025 summer campaign will generate 698,340 new contracts — a 9.4% increase over the previous year and an all-time record that surpasses even pre-pandemic levels. In hospitality alone, that's nearly 247,000 contracts. In retail, another 133,000.
The recruitment machine works. Companies post openings, screen candidates, negotiate terms, and sign. Some do it weeks in advance; others, at the last minute. But they all share one pattern: the investment goes into filling positions, not into making people productive once they're in them.
Onboarding costs get buried in generic budget lines — "training," "HR," "operations" — without anyone isolating them for what they really are: a direct drag on campaign margins. And because it's not measured, it's not managed. According to SHRM, the average cost per hire sits around $4,700, but that figure only captures hard costs (job postings, screening, paperwork). Soft costs — the time a manager spends explaining, supervising, and correcting — account for 60% to 70% of the real cost and rarely make it into any report.
When someone starts an operational role during peak season, they begin generating cost from minute one. But they don't start generating value at the same pace. What happens during those first weeks has an impact that few companies quantify.
Limited productivity. According to Gallup, a new hire operates at just 25% capacity during their first month. Productivity climbs gradually — roughly 50% in month two, 75% in month three — but in a seasonal context, someone who starts in June is barely hitting full output by the time the campaign is winding down.
Supervision time. Shift supervisors and team leads spend an average of 7 extra hours per week explaining tasks, answering questions, and reviewing new hires' work during the first 8–10 weeks. Those hours don't appear as "onboarding cost" — they show up as supervisor hours. But they're hours not spent managing operations, handling incidents, or improving service quality.
Operational errors. Staff without experience makes more mistakes: wrong orders, poorly executed procedures, longer response times. In hospitality and retail, those errors translate into complaints, returns, and — worst case — negative reviews that damage the business's reputation right in the middle of peak season.
Customer impact. A study by the Cornell Center for Hospitality Research found that productivity loss accounts for 52% of total turnover cost — more than recruitment, training, and all other categories combined. It's by far the largest component. And the most invisible.
Over half the cost of each turnover event isn't in hiring someone new — it's in everything that's lost while that person learns how to do their job.
Time-to-Productivity is the period between someone joining a company and reaching a level of autonomous performance — meaning they can carry out their duties without constant supervision. It's not a new concept, but it's a metric the service sector barely uses.
It should, because it's the variable with the greatest impact on a campaign's operating margin.
Consider the numbers. Since Spain's labor reform, the average active period for a fijo discontinuo (the standard seasonal contract) has dropped 44%, from 118 days to just 66 days, according to SEPE data. If full productivity in operational roles takes one to three months to reach, the math is brutal: many seasonal workers finish their contract before they've become profitable.
It's not that they perform poorly. It's that the system isn't built for them to become productive in time. The company invests in sourcing, onboarding, and minimally training them, but the learning curve eats through a substantial portion of the window where they should be generating value.
Time-to-Productivity isn't an HR KPI. It's an operations KPI. Because every extra day it takes someone to work autonomously is a day of additional supervision, avoidable errors, and below-standard service. During peak season, those days are expensive.
The underlying problem is that most companies in the sector don't differentiate between onboarding someone for a permanent role and onboarding someone for a three-month campaign. The needs are radically different, but the process is the same.
Traditional onboarding is designed for long timelines. Gallup estimates that it takes an average of 12 months for an employee to reach full productivity. That may make sense for a permanent position, where the investment amortizes over years. But for a seasonal worker with an active period of 66 days, that timeline is useless.
And yet, 43% of companies compress their entire onboarding into a single day. In hospitality, the picture is even starker: 86% of businesses provide fewer than 10 hours of ongoing training. The practical result is familiar to any shift supervisor: hand them a uniform, walk them through the basics, and send them out to the floor.
Only 12% of employees say their company does onboarding well. And the consequences are measurable: 33% of new hires leave within the first 90 days. In hospitality specifically, that figure rises to 39–42% of front-of-house and back-of-house staff.
This isn't a worker attitude problem. It's a design problem: we're applying a process built for months to a reality that demands results in days.
Seasonal onboarding fails because it's designed for a timeline the seasonal worker simply doesn't have.
Companies solving this problem aren't doing it by training more. They're doing it by making what they already know accessible.
Operational knowledge exists in every service organization — customer service protocols, cash register procedures, food handling standards, presentation guidelines. The problem is the format: it lives in manuals nobody reads, in internal documents that get explained verbally, or purely inside the heads of shift supervisors.
The key isn't creating more training content — it's transforming existing knowledge into formats people can consume on their own, without a supervisor spending hours explaining it. Short, modular videos accessible from a phone before the first day on the job. Formats that let new hires arrive with context, not blank.
Tools like Vidext make it possible to convert operational documentation — from service protocols to food safety procedures — into structured visual content, in multiple languages, without traditional video production. For companies onboarding hundreds of people every season, this turns onboarding from an operational bottleneck into a scalable process.
The data backs the approach. According to Brandon Hall Group, organizations with structured onboarding processes improve retention by 82% and productivity by over 70%. And according to Deloitte, a 10% increase in onboarding investment reduces turnover by 6% — a return that's hard to ignore when you're dealing with campaigns involving hundreds of contracts.
The summer campaign doesn't start when contracts are signed. It starts when those people can serve a customer, handle an issue, or close a register without someone telling them how.
Every day of distance between those two moments is margin lost. And in a sector that generates nearly 700,000 seasonal contracts per year, that distance carries a cost nobody is measuring but everyone is paying.
Time-to-Productivity isn't a trendy metric. It's the lens that reveals a cost we've been absorbing for years without questioning it. Measuring it is the first step to stop accepting it.
Time-to-Productivity is the period from when an employee joins until they reach a level of autonomous performance — working without constant supervision. It can be tracked through operational indicators like error-free task completion rates, average service times, or the ability to resolve issues independently. There's no single standard, but the key is defining what "productive" means for each role and measuring how long it takes to get there.
The average direct cost per hire is around $4,700 according to SHRM, but that figure only reflects 30–40% of the total cost. The rest — supervision, operational errors, reduced productivity — typically gets diluted across other budget lines. Research from the Cornell Center for Hospitality Research puts the total cost of replacing an operational hospitality role at roughly $5,800, with productivity loss accounting for more than half.
Because it's built for long timelines. Conventional models assume 6–12 months to reach full productivity, but a seasonal worker's average active period is 66 days. If the onboarding process isn't specifically adapted to that timeframe — with fast, accessible, self-service formats — the employee spends most of their tenure still ramping up.
The most effective strategy is decoupling training from direct supervision. Instead of relying on a shift supervisor to explain every protocol, you convert operational knowledge into visual, modular content that new hires can access before and during their first days. This frees up supervision time and allows onboarding to happen simultaneously rather than sequentially.
Yes. A 10% increase in onboarding investment can reduce turnover by 6%, according to Deloitte. But beyond retention, the main return is in productivity: cutting the learning curve from four weeks to one means three extra weeks of full output per hire. At scale — with hundreds of contracts per campaign — that difference has a direct, measurable impact on operating margins.
