When Flexibility Splits the Career Ladder
Employment protection legislation is the subject of this series: the rules that govern which employment contracts can be used and how employment can end. The specific question is why the same labour market can offer one group relatively stable, protected jobs while another group cycles through contracts that are easier to terminate. Understanding that relationship lets us judge a temporary job by what it does to a person’s path into stable work—not simply by whether the contract has an end date.
That distinction matters because “flexibility” sounds like a single virtue. For a firm, flexibility may mean being able to adjust staffing when demand falls, technology changes, or costs rise. For a worker, it may mean a first chance to enter the labour market, but it may also mean uncertain income, little training, and no credible route to a permanent position. Both descriptions can be true at once. The policy question is not whether labour markets should adjust. It is who is asked to absorb that adjustment, and whether the arrangement creates mobility or a permanent second tier.
The subject is a set of linked rules
Employment protection legislation is broader than a rule against unfair dismissal. It includes the permitted forms of employment, the conditions under which a contract may be used, and the procedures for ending it. Those procedures can include advance notice, severance payments, special requirements for collective dismissals, and a worker’s right to appeal. Some aspects, such as the length of notice or the amount of severance, are relatively easy to describe. Others depend on how courts interpret a legitimate reason for dismissal or how effectively workers can enforce their rights.
The central comparison is between open-ended employment and temporary employment. An open-ended contract has no predetermined end date; ending it normally requires the employer to satisfy more substantial procedural or financial conditions. A fixed-term contract, by contrast, is designed to end at a stated time or after a defined temporary need, although the precise legal categories vary across countries. Temporary work can also be supplied through an agency, creating a different relationship between the worker, the agency, and the firm where the work is performed.
These arrangements should not be analysed as isolated options. The relevant feature is the distance between them. If an open-ended worker is expensive or procedurally difficult to dismiss while a firm can repeatedly hire temporary workers with few restrictions, the two contracts do not merely offer different degrees of flexibility. They allocate security differently. The open-ended workforce becomes the protected core, while temporary workers become the adjustment margin.
That is the beginning of labour-market dualism: a division between insiders with stronger protection and outsiders with weaker protection. The distinction is not only legal. It can affect the organisation of production, access to training, bargaining power, wages, and the likelihood that a worker will move into a stable job. Younger workers and people with less education are often more exposed because they have a weaker position when seeking entry, though the category “temporary worker” still contains many different situations.
The diagram is deliberately simple. It does not say that a temporary contract always leads to the lower branch, or that an open-ended contract guarantees a good career. It shows why the two rule sets must be considered together: a firm’s choice at one margin changes the meaning of the other margin.
It also helps separate three forms of security that are often blended together. The first is security in a particular job: protection against arbitrary dismissal and access to a remedy. The second is income security during a transition: severance, unemployment benefits, or other support while a person looks for work. The third is career security: the accumulation of skills, experience, earnings, and opportunities that make the next job better than the last. A worker can have one without the others. A temporary contract might offer entry but little career security; a strongly protected job might offer stability while limiting movement to more productive work.
Protection is a balance, not a volume knob
Employment protection exists for reasons that go beyond preserving a worker’s current position. Dismissal can impose costs on a person, a household, and public programmes, not just on the firm making the decision. Rules can discourage arbitrary treatment, require an employer to bear part of those costs, and give a worker time or resources to move to another job. Stable employment can also make it worthwhile for workers to learn firm-specific practices and for firms to invest in training.
But protection can become counterproductive if it makes ordinary adjustment too difficult. A firm facing a fall in demand may respond by hiring fewer people in the first place, retaining workers whose skills no longer fit, delaying the adoption of a new technology, or avoiding a risky market. Higher dismissal costs can reduce both job destruction and job creation. This is why the evidence does not produce a simple rule that stricter employment protection always raises unemployment or always lowers it. The effect on the unemployment rate is uncertain, while the effects on the movement into and out of jobs can be substantial.
The location of flexibility is therefore more important than its existence. Suppose a system makes open-ended employment highly protected but leaves temporary hiring comparatively easy. The firm still has a way to adjust, but adjustment is concentrated among workers with less bargaining power. The result may look flexible in aggregate while offering less protection overall. The social cost has not disappeared; it has moved toward people who are less able to insure themselves, challenge a misuse of the contract, or wait for a better offer.
That is also why a single score for the strictness of employment protection cannot answer the central question. Rules governing dismissal of open-ended workers and rules governing the use of temporary contracts measure different levers. A country can tighten one and leave the other unchanged. Two countries can have similar written rules but different outcomes because courts, labour inspectors, unions, employers, and workers operate with different capacities and incentives. Formal protection is important, but it is not the same as protection that can be used in practice.
The alternative to an uneven protection gap is not a labour market in which every job has identical terms. Firms do face temporary shocks, seasonal needs, and uncertain matches. A functioning system needs a way to test a new employment relationship and to redirect labour when circumstances change. The harder question is whether that flexibility is paired with clear limits, training, worker voice, and a realistic route to a more stable job—or whether it becomes a standing permission to place the risks of adjustment on the same people.
A flexible contract can be a bridge—or a second tier
A temporary contract is most plausibly a bridge when it connects a worker to something that lasts beyond the contract itself. The employer may use the period to screen for a good match, provide training, or respond to a genuinely temporary need. The worker gains experience, skills, and information about the workplace. If the relationship works, conversion to open-ended employment is a credible possibility. In that setting, the temporary period is a stage in a career path, even if not every worker converts.
The mechanism changes when the protection gap is large and temporary work is widespread. The employer can treat temporary workers as a buffer: hire them when demand rises, release them when it falls, and keep the protected core largely insulated. Repeated renewals may then substitute for a decision about a permanent job. Because the worker may leave soon, the firm has less reason to invest in training; because conversion is unlikely, the worker has less reason to invest effort in firm-specific knowledge. The arrangement can reproduce itself, with each short contract making the next stable opportunity harder to reach.
This is the sense in which flexible contracts can create a two-tier career ladder. The problem is not that one rung is temporary. It is that the rungs are connected unevenly. Workers on the lower track may enter employment but receive fewer chances to acquire portable skills, less predictable earnings, and less access to the relationships or representation that help them contest unfair treatment. Meanwhile, insiders may retain the training, bargaining power, and stability that make further advancement easier. A labour market can therefore show frequent hiring and still fail to provide meaningful upward movement.
The available evidence supports a conditional conclusion rather than a universal one. Temporary contracts have acted as stepping stones in some settings and as dead ends in others. The difference is associated with the size of the protection gap, the prevalence and purpose of temporary hiring, the presence of training, the strength of vocational institutions, and the possibility of conversion. Even evidence from countries where stepping-stone effects are more plausible is not uniform. The right question is not “Are fixed-term contracts good or bad?” but “What incentives and institutions determine what happens after the contract begins?”
That question keeps the subject in view while avoiding two opposite mistakes. Treating every temporary contract as exploitation ignores legitimate short-term work and the possibility of screening or training. Treating temporary work as harmless flexibility ignores the way repeated insecurity can shape productivity, wages, and a worker’s whole career. The line between the two is not drawn by rhetoric. It is revealed by what happens to hiring, renewal, training, conversion, income, and exit.
This series follows that line through the architecture of employment protection and the evidence on its consequences. The next necessary step is to look closely at the rules themselves: where notice, severance, dismissal procedure, and restrictions on temporary hiring place the costs of adjustment. Only then can we see how a difference between two contract forms becomes a durable difference in people’s chances.
