Back to work: How part-time reintegration helps

Part-time reintegration can ease the return to work after a long illness. What employees should clarify before agreeing to it.

An employee plans a phased return to an Austrian workplace after a prolonged illness

As of: 27 June 2026.After a longer period of sick leave, the first full working day is often challenging not only organizationally but also in terms of health. Many employees want to return to work but find that eight hours, full responsibility and all old routines at once can be too much. This is precisely where part-time reintegration (Wiedereingliederungsteilzeit) comes in. It enables a temporary return with reduced working hours, a clear agreement and financial security through the reintegration allowance.

Important: part-time reintegration is not an extended sick leave and not an automatic benefit. It requires preparation, a medical assessment, a written agreement with the employer and approval by the health insurance provider. Those who plan the process carefully can avoid being overwhelmed while staying connected with the team.

What part-time reintegration is meant to achieve

The Wiedereingliederungsteilzeit, often abbreviated WIETZ, is intended for employees who are fit for work again after a longer illness but should not immediately resume full hours. The Ministry of Social Affairs describes it as a gradual return to working life with reduced working hours, clear framework conditions and financial support. The purpose is not to reduce performance but to enable a stable reintegration.

This is an important distinction. Anyone still on sick leave should not improvise part-time work on the job. Only when the ability to work has returned and a return is medically sensible does part-time reintegration become relevant. It is especially helpful after illnesses, operations, psychological strain or accidents, when everyday life needs to be rebuilt.

For employees the benefit is practical: working hours, timing of shifts, duration and procedure are determined in advance. For employers it also creates more predictability, because return, tasks and workload are not decided spontaneously on the first day.

What requirements are important in Austria

The central prerequisites are described largely the same in the official information. An active employment relationship is required that has existed for at least three months before the start of the reintegration part-time work. The sick leave must have lasted at least six weeks continuously. In addition, the reintegration part-time work must generally begin within one month after the end of the sick leave.

In addition, a reintegration plan, a written agreement with the employer and a medical statement or occupational health assessment are required. Advice from fit2work plays an important role; according to the Ministry of Social Affairs, under certain conditions it can be replaced by the approval of occupational medicine or an occupational health centre.

The Chamber of Labour additionally points out that employees must be fully fit for work. That sounds contradictory, but it is the core of the model: one is no longer on sick leave, but needs a reduced workload for a limited time so that the return is successful and healthy.

No automatic entitlement: the employer must cooperate

A common misconception is the assumption that employees could unilaterally demand reintegration part-time work. The Business Service Portal states that there is no legal entitlement to its implementation. Employees and employers must agree on it. Precisely for this reason, the conversation should not begin only on the last day of sick leave.

Practical, factual preparation helps. Employees should not only say that they need fewer hours, but also explain how the return can work: Which tasks are realistic to start with? Which appointments are critical? Which activities should be temporarily reduced? What handovers does the team need?

Those who are unsure can seek advice before the conversation. Works council, Chamber of Labour, fit2work, treating physicians or occupational medicine can help formulate a viable plan. The jobspot.at-article Addressing conflict at work: When a conversation really helps shows additionally how sensitive workplace issues can be prepared in a factual manner.

Working hours: Reduction needs clear boundaries

During part-time reintegration, working hours are temporarily reduced. fit2work suggests a reduction of 25 to 50 percent of the contractually agreed working hours, with at least twelve hours per week remaining. The exact distribution is not just a detail: it determines whether the return actually relieves the employee or merely compresses the same work into less time.

A good agreement therefore clarifies not only the number of hours but also the scheduling of working time. Three short days can feel different from two long days. Fixed times can be important for therapies, check-ups, or recovery. For office and knowledge work, it should also be agreed how to handle meetings, emails, on-call duties and spontaneous additional tasks.

Anyone who already had overtime or hard-to-plan days before the sick leave should not adopt those patterns without comment. Working hours and workload belong together. To provide a comprehensible basis, it can help to document working hours and extra work clearly. The article that fits this is "Recording working hours: Why keeping a record on the job matters.

Plan duration and extension realistically

Part-time reintegration can initially be agreed for a period of one to six months. If it remains medically sensible, a single extension of one to three months is possible. The period should be estimated neither too short nor too long.

A plan that is too short creates pressure if the body or mind needs more time. Conversely, a plan that is too long without clear stages can leave it unclear when which tasks will be resumed. A stepwise model is therefore sensible: start with reduced workload, review after a few weeks, then possibly adjust hours, tasks or responsibilities.

It is also important to consider which work may actually remain undone during the reduced period. If the same goals, the same deadlines and the same availability are expected, this does not create a healthy reintegration but rather an intensification of work. That should be addressed in advance.

Reintegration allowance and income

During reduced working hours, the employer pays the pro rata pay for the work actually performed. In addition, reintegration allowance from health insurance may be added. The ÖGK states that this is calculated from the increased sickness benefit and paid out depending on the extent of the reduction in working hours.

For employees it is crucial to understand in advance not only the hours but also the financial impact. Anyone who significantly reduces their weekly working hours will receive correspondingly less pay from the employer. The reintegration allowance is intended to mitigate the income loss, but it does not simply replace the full previous salary.

Tax and social security details can also be relevant. Social insurance provides information on this, among other things from the employer's perspective. Those on a tight budget should ask before signing which amounts can be expected approximately and when the payment will be made.

The reintegration plan: not just a formality

The reintegration plan is more than a form. It should describe concretely how the return should look: start, duration, extent of part-time work, scheduling of hours, possible stages and medically appropriate limits. The more precise the plan is, the less room for interpretation there will be later in everyday work.

Good questions to prepare with are: Which tasks are feasible at the beginning? Which tasks should wait? Are there strains that are particularly sensitive from a medical perspective? Which appointments can be postponed? Who will cover duties during the transition phase? How will the team be informed without disclosing private diagnoses?

Employees do not have to explain every medical detail to the employer. What matters is which working conditions are agreed for the return. Illness, diagnosis and private health data should only be discussed to the extent necessary for planning and processing.

Before the conversation with the employer

If you want to raise reintegration part-time, choose the sequence deliberately. First clarify medically whether a phased return is sensible. Then obtain information from fit2work, ÖGK, the Arbeiterkammer, or occupational medicine. After that, you can formulate a concrete proposal for the employer.

A good way to start the conversation might be: "I would like to return steadily after my sick leave. Medically, a phased return is sensible. I would like to explore whether we can agree on a reintegration part-time arrangement with a clear schedule and task planning." This is not about special treatment, but about a planned return process.

If there are still outstanding reporting or documentation obligations during the sick leave, these should be properly completed first. The basics for that are explained in the article Reporting sick leave: What really matters at work.

If the plan doesn't fit

Not every return goes smoothly. Sometimes the planned number of hours is too high, tasks are more demanding than expected, or the team expects a return to normal performance too quickly. In that case, you shouldn't just tough it out silently. It's better to give early feedback: What is working? What is overwhelming? What change would be realistic?

If employer and employee cannot find common ground, the works council, the Arbeiterkammer, or fit2work can provide advice. Treating physicians and occupational medicine should also be involved when health limits are reached. The crucial point is not to address problems only at the end of the agreement.

If, after returning, you notice that the workplace fundamentally no longer fits, you should still not act hastily. First stability, then decision. For a later change, it helps to examine an offer carefully. The article Don't rush an acceptance: How applicants evaluate a job offer.

Checklist for employees

  • Medically determine whether a phased return is appropriate.
  • Check whether the employment relationship and the length of sick leave meet the requirements.
  • Involve fit2work, occupational health services, ÖGK or the Chamber of Labour early.
  • Prepare concrete working hours, tasks and limits on workload.
  • Thoroughly review the written agreement and reintegration plan.
  • Clarify the financial implications of reduced pay and any reintegration allowance.
  • Assess progress after a few weeks and raise any need for adjustments in good time.

Conclusion: A return is a project, not a jump into cold water.

A phased part-time return to work can be a sensible way back to the job after a long illness. But it only works if it is planned seriously: medically, in terms of work organization, and financially. Employees should clarify early on whether the prerequisites are met, which hours are realistic, and who will confirm the next steps. Employers also benefit when the return is stable and does not result in sick leave again after just a few weeks.

Those affected should not have to navigate alone between medical clearance, meetings with the employer, and paperwork. Good advice before making an agreement prevents later conflicts. The most important step is a concrete plan: which work is possible now, which is not yet, and when you will jointly review whether the approach is working.
