Trial Period: Legal Timeframes and Termination

Introduction

The trial period is a pivotal phase of the employment contract: it allows the employer to assess the employee's competencies and allows the employee to evaluate their new employment conditions. Governed by employment law, it is subject to precise rules regarding duration, renewal and termination conditions. Any failure to comply with these legal timeframes exposes the company to costly employment disputes. In this article, we review the legal durations applicable according to professional category, renewal arrangements, mandatory notice periods and best practices for formalising and securing the termination of the trial period.

Legal Durations of the Trial Period Under Employment Law

The maximum durations of the trial period are set by law and vary according to the professional category of the employee recruited on a permanent contract.

Legal Durations for Permanent Positions

• Operational and support staff: 2 months

• Team leaders and technicians: 3 months

• Senior managers: 4 months

These durations are legal maxima. An enterprise agreement or award may provide for shorter durations — never longer. It is therefore necessary to systematically consult the applicable enterprise agreement before drafting the employment contract.

Special Case of Fixed-Term Contracts

For fixed-term contracts, the duration of the trial period is proportionate to the duration of the contract: one day per week up to a maximum of two weeks for contracts of six months or less, and one month for contracts exceeding six months. Electronic signature of employment contracts now allows immediate formalisation of these clauses, timestamped and archived in a legally probative manner.

Trial Period and Apprenticeship or Traineeship Contracts

Apprenticeship contracts do not include a trial period in the strict sense. However, the first two months of the contract constitute a period during which either party may terminate without formal requirement. Traineeship contracts follow the rules of fixed-term or permanent contracts according to their nature.

Renewal of the Trial Period: Conditions and Formalities

Renewal of the trial period is only possible if three cumulative conditions are met:

• An enterprise agreement or award explicitly authorises it.

• The employment contract must explicitly mention the possibility of renewal from its conclusion.

• The employee's express consent must be obtained before the expiry of the initial period.

Maximum Durations After Renewal

After renewal, total durations cannot exceed:

• Operational and support staff: 4 months

• Team leaders and technicians: 6 months

• Senior managers: 8 months

These ceilings are mandatory: no individual agreement may exceed them. A renewal carried out without the employee's express consent or beyond these durations will be reclassified by employment tribunals, exposing the employer to damages. To secure this consent, the use of a tool for electronic signature compliant with eIDAS regulation guarantees irrefutable traceability.

The Notion of Fictitious Trial Period

Case law regularly sanctions employers who unlawfully extend the trial period to defer the protections related to termination. An excessively long or renewed trial period without a contractual basis may be reclassified as termination without a valid reason.

Notice Periods Upon Termination of the Trial Period

The termination of the trial period is at will: neither the employer nor the employee must justify it. However, mandatory notice periods apply.

Notice Periods Required of the Employer

When the employer terminates the trial period, it must observe a notice period whose duration varies according to the employee's length of service in the company:

• Less than 8 days of service: 24 hours

• Between 8 days and 1 month of service: 48 hours

• Between 1 and 3 months of service: 2 weeks

• Beyond 3 months of service: 1 month

These periods are calculated in calendar days. Failure to observe the notice period does not invalidate the termination but entitles the employee to compensation equal to the wages they would have earned during this period.

Notice Periods Required of the Employee

When the employee initiates termination of the trial period, they must notify the employer:

• 48 hours before departure

• 24 hours if the period of service in the company is less than 8 days

These periods are significantly shorter, reflecting the mobility freedom granted to the employee during the trial period. Termination notification may be formalised by registered letter with acknowledgement of receipt or, increasingly, by qualified electronic signature, which provides a certain date and opposable evidence.

Consequences of Non-Compliance with Notice Periods

The employer's failure to observe notice periods constitutes a breach that may engage its contractual liability. It is established that termination notified outside business hours or days may be deemed improper if it reveals an intent to cause harm.

Formality of Termination and Security Through Electronic Signature

Whilst the law does not require any particular form for the termination of the trial period — it can theoretically be verbal — prudence recommends a written, dated and signed document. In practice, HR professionals increasingly favour documented processes for several reasons.

Why Formalise Termination in Writing?

• Proof of notification date: the notice period runs from receipt of notification. A timestamped written document avoids any dispute over the starting point.

• Proof of unambiguous intent: case law accepts verbal termination, but its proof is difficult to establish if the employee contests it.

• Conservation of traceability: secure electronic archives allow instant retrieval of any document in case of dispute.

Integration into a Digital HR Process

Electronic signature solutions dedicated to human resources enable automation of sending, signature and archiving of documents related to the trial period: renewal letter, employee's express consent, termination notification. The evidentiary value of an advanced or qualified electronic signature within the meaning of eIDAS Regulation (EU) No 910/2014 is recognised by employment tribunals, as recalled in the comprehensive guide to electronic signature in business.

For companies managing numerous simultaneous recruitments, the use of a calculator for the ROI of electronic signature makes it possible to precisely quantify the HR productivity gains linked to the dematerialisation of these formalities.

Points of Particular Attention in 2026

Interaction Between Trial Period and Sick Leave

Suspension of the employment contract for extended illness extends the trial period accordingly, unless an agreement provides otherwise. An employee absent for 15 days due to illness sees their trial period extended by 15 calendar days. This rule, confirmed by case law, is often overlooked by employers.

Non-Compete Clause and Trial Period Termination

Termination of the trial period ends the employment contract but does not necessarily eliminate a non-compete clause if it has been validly stipulated. However, many enterprise agreements provide that the non-compete clause does not apply in the event of termination during the trial period, subject to express waiver within agreed timeframes.

Trial Period and Confidentiality Agreement

Where an employee has had access to sensitive information from the outset of their employment, termination of the trial period does not eliminate confidentiality obligations. These commitments, ideally signed from day one via a secure electronic signature solution, remain enforceable after the end of the contractual relationship.

Legal Framework Applicable to the Trial Period

Employment Law

The trial period is principally governed by employment law provisions, which set maximum durations, renewal conditions and notice periods. These provisions are mandatory, meaning no individual or collective agreement may derogate from them to the employee's detriment.

Employment law defines the trial period as allowing the employer to evaluate the employee's competencies in their work, and the employee to assess whether the functions suit them. Its presence in the contract is not automatic: it must be expressly stipulated, otherwise the contract is considered definitive from hire.

Case Law

Employment courts have rendered several structuring judgements:

• Termination notified under vexatious conditions may constitute a breach causing distinct harm, even if the termination itself is at will.

• Suspension of the contract for illness postpones the end of the trial period.

• Renewal without the employee's express consent is unenforceable.

Probative Value of Electronic Documents

In accordance with employment law and civil law principles, an electronic written document has the same evidentiary force as a paper document, provided that the identity of the person from whom it emanates is duly assured and the document is established and retained under conditions designed to guarantee its integrity. Electronic signature consists of the use of a reliable identification process guaranteeing its link with the act to which it is attached.

eIDAS Regulation (EU) No 910/2014, applicable in Australian employment law context through mutual recognition principles, establishes three levels of electronic signature (simple, advanced, qualified). For common HR documents such as trial period renewal or termination letters, an advanced electronic signature is generally sufficient. A qualified signature, compliant with applicable standards and delivered by a qualified trust service provider, offers the highest presumption of reliability.

Privacy and Candidate Data

Personal data collected during the trial period (evaluations, exchanges, HR documents) are subject to privacy legislation. The employer must inform the employee of the processing of their data, its retention period and their access and deletion rights. The retention period for documents relating to termination is aligned with the limitation period for employment disputes, set at two years.

Usage Scenarios: Formalising the Trial Period with Electronic Signature

Scenario 1 — A Mid-Sized Industrial Company with High Operator Turnover

A mid-sized industrial company hires on average 40 operators and team leaders per year. Each recruitment generates several documents to be signed: employment contract with trial period clause, workplace policies, confidentiality agreement, and, if applicable, renewal or termination letter. With a paper process, the average time between the HR decision and actual document signature reached 4 business days, exposing the company to the risk of failing to observe legal notice periods.

By deploying an advanced electronic signature solution integrated with its HR system, the company reduced this timeframe to less than 2 hours. Each document is timestamped, automatically archived and accessible in case of dispute. The error rate on notice periods fell to zero over the 18 months following deployment. According to HR estimates, the productivity gain represents approximately 1.5 full-time equivalents per year.

Scenario 2 — A Management Consulting Firm Managing Senior Manager Profiles with High Turnover

A management consulting firm of 80 consultants, with a majority of senior managers, experiences high turnover (approximately 25% per year). The trial period for senior managers is 4 months, renewable once up to 8 months subject to agreement. The firm had encountered two employment tribunal disputes in three years related to poorly formalised renewals: employee consent obtained verbally or after expiry of the initial period.

Since adopting a digital workflow with electronic signature, each step is triggered automatically 15 days before expiry: the employee receives an email proposing to sign their renewal consent electronically, with a 5-day response period. In the absence of signature, the trial period is not renewed. This process has eliminated all renewal-related disputes since its implementation, representing estimated savings of between AUD 8,000 and 15,000 in legal advice and dispute costs per year, according to industry benchmarks.

Scenario 3 — A Public Hospital Network Managing Multiple Facilities

A public hospital network of approximately 1,200 staff members hires several hundred contract workers annually for nursing and administrative positions. Even if public sector law applies different frameworks, the trial periods for contract staff are governed by comparable principles. The dematerialisation of trial period completion letters has reduced processing time from 6 days to 1 business day, whilst guaranteeing the traceability required by regional audit requirements.

Conclusion

The trial period is a precise legal mechanism that leaves no room for approximation: maximum durations set by law, renewal conditional on threefold agreement, mandatory notice periods calculated to the day. Any procedural error can transform into costly employment tribunal proceedings, with reclassification as termination without valid reason at stake.

The good news is that the dematerialisation of HR processes — and notably the use of electronic signature — now enables automation of these formalities whilst guaranteeing their probative value. Each document is timestamped, archived and enforceable.
