How do I address a gap in a cover letter?

Updated: 23 August 2026

In short

Give it one sentence and end it in the present. State the period in months and years, name what it held in a single noun, and finish with the date you are free to start. You do not owe anyone the reason: under Art. 328b of the Code of Obligations an employer may handle data about you only insofar as it concerns your suitability for the job. Your CV dates the gap. The letter points it forward. Saying the same thing twice is the actual mistake.

Swiss applications make this easier than most, because the arithmetic is already on the table. Every reference letter, under Art. 330a para. 1 CO, states the nature and duration of the employment relationship, and Swiss dossiers carry those references as attachments. The reader can therefore see your start and end dates without you narrating them. A letter that repeats those dates adds nothing; a letter that adds one date they do not have — the day you can begin — adds the only piece of timing information the advert usually leaves open.

That last point is measurable. Across the Swiss adverts we index that carry a short description, 0.6 percent mention a start date or availability at all, and only 0.4 percent of advert titles do. Meanwhile 76.4 percent mention experience of some kind, but just 5.2 percent attach a number of years to it. The criterion a gap supposedly breaks — unbroken years — is rarely the criterion being applied, and the field you can actually fill is the one nobody filled in for you.

What Swiss adverts state, and what they leave to you

Share of the Swiss adverts we index that carry a short description; rolling count, August 2026. English-language adverts are counted separately in the third bar. A missing term means «not emphasised», not «never mentioned».

Three parts, one sentence: the period in months and years, one noun for its content, one date for your availability. «From March to September 2026 I completed a certificate in financial accounting; I am available from 1 October.» That is the whole treatment.
Put it where the timing lives. A Swiss letter's second-to-last paragraph is the organisational one — start date, workload, notice period. The gap sentence belongs there. In the opening line, the identical wording turns the gap into the headline of your application.
The reason is not owed. Art. 328b CO: «The employer may handle data concerning the employee only to the extent that such data concern the employee's suitability for his job or are necessary for the performance of the employment contract.» A diagnosis does not concern suitability. A return to full fitness does.
Family reasons least of all. Art. 3 para. 1 of the Gender Equality Act forbids discrimination «including on the basis of their marital status, their family situation or, in the case of female employees, of pregnancy», and para. 2 states that the prohibition applies «in particular to hiring» — that is, to the process your letter is being read in.
The Act even prices the case. Where discrimination consists in a refusal of employment, Art. 5 para. 2 gives the person concerned a claim to compensation, capped by para. 4 at an amount equivalent to three months' salary. You are not writing into a legal vacuum.
Cut «unfortunately», the conditional and the pre-emptive question. «You may be wondering why…» creates the doubt it was meant to settle. A dated clause in the indicative closes it.
Under three months, say nothing. Notice periods and holidays routinely leave four to eight weeks between jobs; a sentence about that invents a subject rather than resolving one.

Why the sentence is short: the dossier already did the counting

A Swiss application is not a marketing document with attachments, it is an index to a stack of evidence: CV first, then reference letters, diplomas and certificates. Because Art. 330a para. 1 CO entitles every employee to a reference covering the nature and duration of the employment relationship, that stack is dated by law. Whatever your letter says or omits, the timeline is legible from the attachments.

This is why the confessional cover letter fails so reliably here. Three paragraphs of context do not add information to a reader who can already see the dates; they only change the subject of the letter from the job to you. And the opposite tactic — silence — fails for the same structural reason: the dates are visible whether or not you mention them, so silence reads as avoidance rather than discretion.

The official guidance stops before this question, which is worth knowing so you do not go looking for a rule that does not exist. arbeit.swiss, the SECO job-seeker portal, describes what the letter is — «The cover letter is your personal business card. It gives you the opportunity to demonstrate your communication skills and express yourself» — and then lists the formal elements it should contain: your postal address, the company's postal address, date, subject heading, opening salutation, closing greeting and signature. Nothing about career breaks.

So the working rule has to come from what is checkable: the dossier dates the gap, the law limits what may be asked about it, and the advert tells you what is actually being tested. One sentence is what survives all three.

Building the sentence

Part one is the period, written the way your CV writes it — month and year, no adjectives. Part two is a noun that names the content: further education, caring responsibilities, recovery, relocation, job search. Part three is a date, or the word «immediately». A sentence built from those three parts cannot beg, and begging is the failure mode that costs interviews.

Worked versions for the common cases. Study: «Between March and September 2026 I completed the Swiss certificate in payroll accounting and am available from 1 October.» Care: «From January to July 2026 I cared for a family member; that period has ended and I can start immediately.» Health: «I have been fully fit for work again since June 2026.» Relocation: «I moved to Switzerland in April 2026 and have been looking for a permanent role here since.» Redundancy: «My role was cut in a restructuring at the end of May; I am available at short notice.»

One extra sentence is allowed, on one condition: the gap produced something that qualifies you for this advert. A completed course with a provider and a date, a language level you can name, a volunteer role with real responsibility. That is evidence of the same kind you would give for a job. Anything that fails that test — hobbies, self-reflection, plans — stays out.

For a gap that is several years old and followed by steady work, drop the sentence entirely. The letter is about this job; a break that has already been closed by two subsequent employments is a question for the interview at most, and reviving it in writing gives it a weight the timeline no longer supports.

What the advert is really testing

The fear of the gap rests on an assumption you can check against the adverts themselves: that employers count unbroken years. Mostly they do not. Of the indexed Swiss adverts carrying a short description, 76.4 percent mention experience in some form, but only 5.2 percent quantify it in years — and of every advert that mentions experience at all, 93.2 percent never states a number. What is being asked for is a kind of experience, not an amount of it.

Language matters more than sector here, and it matters especially if you apply in English. German-language adverts put a number of years on experience in 0.7 percent of cases; French-language ones in 9.9 percent, Italian-language in 7.0, and English-language adverts in 12.5 percent — roughly one in eight. International employers advertising in English import the «5+ years» convention along with the language, so the number you are defending is far more likely to appear in an English advert than a local one.

When a number does appear, five years is the most common demand, at 34.3 percent of quantified adverts, followed by three years at 21.1 and two at 11.5. Answer it arithmetically rather than defensively: count relevant years, not calendar years since graduation, and write the result — «six years in accounts receivable, four of them closing the books». The gap is neither added nor subtracted; it sits dated in the CV, which is where it belongs.

One more silent expectation is worth planning for. Only 2.1 percent of the short descriptions we index mention induction, onboarding or a training-in period. If you are returning after a long break, put one line of evidence in the letter that the reconnection has already happened — a current certification, a recent course, a temporary assignment. Not as an apology, but as proof that the ramp-up is behind you rather than ahead of the employer.

What you never have to explain

The limit on what an employer may process about you is written into the employment contract law itself. Art. 328b CO: «The employer may handle data concerning the employee only to the extent that such data concern the employee's suitability for his job or are necessary for the performance of the employment contract. In all other respects, the provisions of the Data Protection Act of 25 September 2020 apply.» That line is a useful editing tool: if a clause in your draft does not bear on suitability, it does not need to be there.

For health-related breaks the rule translates into a phrasing rule — write the return, not the diagnosis. «Fully fit for work since June 2026» is the statement that concerns suitability. The illness, the treatment and the prognosis do not, and putting them in writing invites a conversation that has no upside for you and no legal basis for them.

For family-related breaks the Gender Equality Act adds a second layer. Art. 3 para. 1 prohibits direct and indirect discrimination on the basis of sex, «including on the basis of their marital status, their family situation or, in the case of female employees, of pregnancy»; para. 2 applies the prohibition «in particular to hiring, allocation of duties, setting of working conditions, pay, basic and continuing education and training, promotion and dismissal». Hiring is named first, so the letter is squarely inside the protected process.

And the Act attaches a number to it. If the discrimination consists in a refusal of employment, Art. 5 para. 2 entitles the person concerned to compensation, which under para. 4 must not exceed three months' salary. None of this is an argument to make in a cover letter — it is a reason not to write your letter as a request for permission. A parental break is a period with an end date, not a plea.

If the gap is still open

A current, unfinished gap is the easiest version to write, because it is in the present tense and ends in a date you control. «I have been looking for a permanent role since May 2026 and can start immediately» is complete. Immediate availability is the one circumstance in which a break becomes an advantage in the letter — and given that 0.6 percent of adverts say anything about timing, it is an advantage you have to raise yourself or lose.

If you are still serving notice, put that in the same paragraph as a date rather than a duration. «Available from 1 December» can be checked against a calendar; «three months' notice» asks the reader to do the arithmetic, and readers under time pressure skip arithmetic. Where both matter, lead with the date and add the notice period in brackets.

Workload is the other lever, and Swiss adverts are unusually explicit about it: 22.1 percent state a workload in the title, and in 73.5 percent of those the lower bound is below one hundred percent — 45.7 percent start at 80 to 99 percent, 18.5 percent at 50 to 79, 8.6 percent at 20 to 49. Returning at a reduced percentage is therefore not something you have to negotiate against the grain; on many adverts the range is printed in the title, and «starting at 80 percent, moving to full time from January» lands inside it.

Do not wait for a bridge role to advertise itself, either. Only 0.9 percent of the advert titles we index flag a maternity cover, a fixed-term assignment or a temporary contract. Those bridges exist, but they are mostly invisible at the title level — you reach them by applying, not by searching until the perfect posting appears. And when the letter is finished, apply one test: if the break is the first thing you remember about your own letter, delete a sentence. It is usually one sentence too long.

Market figures come from our rolling count of the Swiss job adverts we index, as of August 2026. The counts for experience, years, induction and availability are taken from those adverts that carry a short description — close to three quarters of the stock — so a missing term means «not emphasised» rather than «never mentioned». The workload and temporary-assignment figures are read from advert titles verbatim. We publish shares, never absolute stock figures, and rounding differences are possible. Legal references are taken from the Code of Obligations and the Gender Equality Act as published on fedlex.admin.ch; the English versions there are unofficial translations, and none of this is legal advice.
