Common or occupational: why it matters
Sick leave can stem from a common cause or an occupational one — that is, a work accident or an occupational illness. The difference affects the amount of benefit, who manages it (often the employer’s collaborating mutual insurer, or mutua) and possible employer liability.
If you believe your leave should be classified as occupational but it has been processed as common, there is a procedure to determine the cause. Accidents in itinere, on the way to or from work, can also count as work accidents.
During temporary incapacity
While you are on sick leave your contract is suspended, not terminated. The employer cannot dismiss you simply for being on leave, although it may take decisions on other grounds that deserve close examination. Medical discharges you disagree with can be challenged within very short deadlines.
Keep sick-leave certificates, medical reports and communications from the mutua and the National Social Security Institute (INSS). Medical documentation is the backbone of any later claim.
Permanent incapacity and lasting effects
When limitations persist, a permanent incapacity procedure can be opened before the INSS, with different degrees — partial, total, absolute or severe disability — and very different effects on employment and benefits. Decisions can be reviewed through a prior administrative claim and then a court claim.
Some injuries give rise to scheduled lump-sum payments. If the accident happened because safety measures were lacking, a benefits surcharge (recargo de prestaciones) and a damages claim against the employer may be considered.
Returning to work
Returning may require adapting the role, changing duties or an assessment by the occupational health service. Employees who are especially sensitive to certain risks are entitled to specific protection.
My role is legal: reviewing employment and Social Security documents, explaining the available routes and their deadlines, and coordinating with your healthcare professionals where needed. It does not replace medical judgement, but it translates it into informed employment decisions.
Deadlines that catch people out
In incapacity and Social Security matters, deadlines are particularly short and vary by procedure: disagreeing with a medical discharge, filing a prior claim against an INSS decision or requesting a determination of the cause of leave each follow their own timetable. Some notifications also arrive electronically and start running even if they are not opened. Reviewing each notice as soon as it arrives is the best way to avoid losing options over dates.
Disagreeing with a medical discharge
Sometimes temporary sick leave is ended with a medical discharge while the worker still feels unable to work. There are procedures to express disagreement with a discharge issued by the social security medical services, and they have very short deadlines counted in days. Missing them usually means returning to work or facing absence issues. If you disagree with a discharge, act the same week.
Degrees of permanent incapacity
Permanent incapacity is graded. Partial incapacity reduces performance in your usual job; total incapacity prevents you from doing your usual job but allows another; absolute incapacity prevents any job; severe disability requires help from another person for basic activities. The degree recognised determines whether a pension is paid and its amount, and also what happens with your employment contract.
Resolutions from the National Social Security Institute can be challenged. A prior administrative claim must normally be filed before going to court, within the deadline stated in the resolution itself. Medical reports from specialists, describing limitations in functional terms rather than only the diagnosis, are often what change the outcome.
Your job while on sick leave
Being on sick leave does not, in itself, prevent dismissal, but a dismissal motivated by illness can be discriminatory and treated accordingly. If you are dismissed while on leave, or shortly after returning, the timing and reasons deserve careful review.
Work accident or common illness
Whether a sick leave or incapacity is classified as resulting from a work accident or occupational disease, or from a common illness, changes the benefit amount, the contribution requirements and the possibility of additional claims against the employer, such as the surcharge when safety measures were missing. The classification initially given is not always correct and can be disputed. If your condition started or worsened because of your work, gather evidence of how and when as early as possible, including incident reports and witness names.
Useful documents for a first review
- Sick-leave, confirmation and discharge certificates
- Medical reports and mutua reports
- The work-accident report, if one exists
- INSS decisions
- The risk assessment for your role, if you have it
- Communications from your employer during the leave
What to expect from the first conversation
In our first contact you tell me what happened and what worries you. I will tell you whether any deadline requires immediate action, which documents to gather and, broadly, which routes are available. If we decide to work together, you will receive the scope of the engagement and the fees in writing before anything starts.
You do not need to have everything in order or know the legal name for your situation — that is precisely my job. The one thing that matters is not letting time slip by when deadlines are involved. I work in Spanish, Catalan and English.
Frequently asked questions
Can I be dismissed while on sick leave?
Being on sick leave is not a ground for dismissal. A dismissal during leave must be examined carefully, because in some cases it may be considered discriminatory.
What if I am signed fit for work but cannot work?
There are ways to challenge a medical discharge, with very short deadlines. Seek advice as soon as you receive it.
What is the benefits surcharge?
It is an increase in benefits payable by the employer when an accident or illness results from a failure to provide safety measures.
