One of the greatest challenges facing owners and managers of small and medium-sized enterprises (SMEs) is attracting and retaining qualified professionals. In a highly competitive market, competing with large corporations for experienced talent can put considerable pressure on an SME’s cash flow, particularly when those corporations offer higher salaries and comprehensive benefits packages. In addition, experienced professionals may arrive with established working habits and be resistant to the company’s internal methods. 

In this context, developing talent through structured internship programmes has become one of the smartest and most accessible tools for corporate development. More than an alternative for meeting operational needs, SMEs should view internships as an incubator for future leaders and analysts, tailored to the organisation’s culture, values and processes. 

However, structuring an internship programme requires technical rigour and compliance with Brazilian employment and education legislation. Treating an intern as a ‘cheaper CLT employee’ is one of the most dangerous management failures, capable of generating significant legal liabilities and undermining the initiative’s educational purpose. 

In this comprehensive guide, we will explore the advantages and disadvantages of opening internship vacancies in your SME, the legal limits on duties and responsibilities under Brazil’s Internship Law, the mandatory requirements for the company and the student, and the metrics for assessing the right time to offer permanent employment. 

Advantages and Challenges of Launching an Internship Programme in Your SME 

The decision to open your company’s doors to university or technical-course students offers substantial benefits, but it also imposes operational responsibilities that leadership must weigh carefully. 

Strategic Advantages for Small and Medium-sized Businesses 

• Fresh Thinking and New Perspectives: Students bring up-to-date academic knowledge, familiarity with new technologies, digital tools and modern methods. Their questioning energy helps identify outdated processes and propose creative solutions to routine bottlenecks. 

• Development Aligned with Company Culture: In terms of corporate routines, an intern is a blank slate. The SME has a unique opportunity to shape this talent according to its ethical values, service standards and business vision, creating loyal professionals without habits acquired in other organisations. 

• Lower Operating Costs and Exemption from Employment Charges: An internship agreement does not create a conventional employment relationship. The company is exempt from charges such as FGTS, the employer’s INSS contribution, notice pay and the 40% termination penalty. Although interns receive an internship allowance and travel allowance, the total cost is substantially lower than that of a permanent employee. 

• Building a Reliable Succession Pipeline: An internship works as an ‘extended probationary period’ of up to two years. At the end of this cycle, the company can confidently employ permanently a professional who already understands the operation, eliminating the costs and risks of external recruitment for junior vacancies. 

Challenges and Disadvantages of the Model 

• Need for Dedicated Mentoring and Supervision Time: Interns do not arrive fully prepared. A manager or senior professional must set aside hours each week to guide, teach, answer questions and monitor tasks. If the SME has an overstretched team with no time to teach, the internship programme will fail. 

• Working-Hour Restrictions and Staff Turnover: Interns work reduced hours, generally six hours per day, and are entitled to leave earlier during examination periods. Moreover, as the agreement may last no more than two years by law, the company must deal with turnover if no permanent vacancy is available when the student graduates. 

• Initial Learning Curve: In the first few months, an intern’s productivity will be low while they learn the company’s internal routines, tools and systems. Leadership must be patient and understand that the return on investment comes in the medium term. 

Limits on Duties and Responsibilities: What Interns May and May Not Do 

The backbone governing this type of engagement in Brazil is Law No. 11,788/2008 (the Internship Law). The legislation defines an internship as a supervised educational activity whose central aim is to prepare the student for productive employment. 

Ignoring the boundary between an intern’s learning activities and the role of a permanent employee may lead the Labour Court to invalidate the internship agreement and recognise a direct employment relationship under the CLT, with retrospective payment of all employment rights and social-security charges. 

What an Intern MAY Do in the Company 

• Carry out practical activities directly related to the curriculum and field of study—for example, a marketing intern creating content and analysing metrics, or an engineering intern assisting with project surveys. 

• Take part in alignment meetings, internal training and supervised team projects. 

• Produce reports, organise data, carry out preliminary customer service and propose process improvements. 

• Take on progressively greater responsibilities as they demonstrate technical maturity and reliability. 

What an Intern MUST NOT Do under Any Circumstances 

• Work Overtime: Internship hours are strictly limited. Interns may not work overtime, accrue time in lieu or compensate for hours at weekends. 

• Work Alone or without Technical Supervision: An intern must never be left alone as the sole person responsible for a company unit, branch or department. 

• Assume Final Technical Responsibility: They may not sign expert reports, engineering designs, financial statements, legal opinions or medical prescriptions reserved for qualified professionals registered with the appropriate professional body. 

• Perform Tasks Unrelated to Their Studies (Role Misallocation): Interns must not be used for purely clerical or manual work that adds no value to their learning—for example, working exclusively as a driver, stockroom assistant or cleaner when studying business administration. 

• Replace Full Employment Positions: The company may not dismiss a CLT employee and place an intern in the role to perform all the same duties and meet the same targets without direct supervision. 

Mandatory Requirements for the Company and the Candidate 

For the internship programme to be legally valid and operate safely, both the SME and the student must meet a set of formal statutory requirements. 

Requirements for the Student (Candidate) 

• Regular Enrolment and Attendance: The candidate must be at least 16 years old and formally enrolled in and attending a higher-education institution, upper-secondary vocational education programme (technical course), regular upper-secondary school, special education programme or the final years of lower-secondary education under the EJA adult-education scheme. 

• Field Compatibility: The activity plan to be carried out in the company must be directly related to the educational programme of the course in which the student is enrolled. 

Requirements and Obligations for the Host Company (SME) 

• Execution of the Internship Commitment Agreement (TCE): The agreement must be signed by three parties: the Company, the Student (or their legal guardian if under age) and the Educational Institution. Integration agents such as CIEE, Nube and Super Estágios may facilitate the process, but the university’s or school’s signature is indispensable. 

• Mandatory Personal Accident Insurance: The company must take out and pay in full for life and personal accident insurance for the intern, stating the policy number and insurer’s name in the TCE. 

• Appointment of an Internal Supervisor: The company must appoint one of its employees who has a higher-education qualification or proven experience in the intern’s field. Each supervisor may guide no more than 10 interns at the same time. 

• Legally Defined Working Hours: 

  • 6 hours per day and 30 hours per week: For students in higher education, technical courses and regular upper-secondary education. 

  • 4 hours per day and 20 hours per week: For students in special education and the final years of lower-secondary education. 

  • Reduction during Examination Periods: During semester or final assessment periods notified by the university, the intern’s daily hours must be reduced by at least half to allow time for study. 

• Pay and Benefits (Non-compulsory Internship): 

  • Internship Allowance: A mandatory monthly payment in an amount freely agreed by the parties. 

  • Travel Allowance: Mandatory provision of an amount to cover travel costs. 

  • Paid Recess (Holiday): For every 12 months of internship with the same company, the student is entitled to 30 days of paid recess, or a proportionate period if the agreement lasts less than a year, preferably taken during school holidays. 

• Maximum Duration: An internship with the same company may last no more than 2 years, except for persons with disabilities, who may intern with the same organisation for an indefinite period. 

• Periodic Assessment Reports: An activity report must be sent to the educational institution every 6 months, approved by both the supervisor and the intern. 

Assessment and Permanent Employment: How to Decide on the Right Time to Hire 

Offering permanent employment to an intern is the high point of a talent-development programme. It is the moment when all the time and mentoring invested by the company is converted into the permanent recruitment of a professional already adapted to the business culture. 

However, the transition from internship to a formal CLT employment contract requires careful analysis across two complementary dimensions: the student’s performance and the SME’s financial position. 

Dimension 1: Assessing the Intern’s Performance and Maturity 

Before making an offer of permanent employment, leadership should assess the student’s track record on the basis of technical and behavioural competencies (hard and soft skills): 

• Development of the Learning Curve and Autonomy: Does the intern still need constant support for basic tasks, or can they already handle day-to-day demands independently, consulting the supervisor only for final approval? 

• Cultural Alignment and Working Relationships: Does the individual demonstrate commitment to the SME’s values? Do they maintain good interpersonal relationships with colleagues and customers? Do they demonstrate punctuality, ethics and a collaborative spirit? 

• Problem-solving Ability and Initiative: When unexpected situations arise, does the student passively wait for instructions, or do they offer practical suggestions and alternative solutions? 

• Delivery and Technical Reliability: Is their work consistently accurate, attentive to detail and delivered within the agreed deadlines? 

Dimension 2: Assessing the Company’s Position and Cash-flow Planning 

Even with an exceptional intern, permanent employment should only be offered if the SME’s financial structure is ready to absorb the increase in fixed costs: 

• Calculation of the Total Financial Impact (CLT): Remember that a CLT hire involves more than a fixed salary. The SME must account for provisions for the thirteenth salary, holiday pay plus the constitutional one-third supplement, FGTS (8%), the employer’s INSS contribution, transport and additional benefits. The real cost of a permanent employee is around 1.7 to 2.0 times their nominal salary. 

• Existence of Genuine Work Demand: Does the department’s workload justify a full-time professional working eight hours per day and 44 hours per week? Are expansion projects planned for the next 6 to 12 months? 

• Alignment with Graduation: Ideally, permanent employment should be planned to coincide with course completion or the final months of university, allowing the professional to work full time without harming their academic performance. 

If the company cannot absorb the professional at that time, be transparent. Provide references, make introductions to business partners and keep the door open for future opportunities. 

Innovation Beyond People: How NewSun’s Subscription Energy ‘Freezes’ Tariff Uncertainty and Protects Your SME’s Cash Flow 

Developing a talent programme requires business owners to take a bold, forward-looking approach, investing in modern solutions that turn human potential into tangible results. However, the same innovative outlook must be applied to managing the company’s fixed costs. After all, for your SME to have the financial headroom to fund internship allowances, training and new hires, cash flow must be shielded from waste and unwelcome surprises. 

Among the heaviest and most unpredictable operating expenses of a small or medium-sized business, the electricity bill is one of the main sources of uncertainty. Historically, business owners have been at the mercy of local utilities, exposed to repeated tariff increases and spikes caused by tariff flags during periods of drought. 

To break away from this traditional model and bring your company a genuinely original solution, NewSun has revolutionised the market with clean energy by subscription.

You know exactly how much you will save, month after month. 

• No Building Work and No Refurbishment: Forget the bureaucracy of turning your company into a building site. With NewSun, your business does not need to drill walls, change the electrical connection standard or modify the property’s infrastructure. 

• No Investment in Equipment (Zero CAPEX): You do not need to spend thousands of reais from working capital on solar panels, batteries or inverters. Your cash remains available for investment where it truly generates returns: purchasing stock, adopting technology and hiring new talent. 

• No Maintenance Concerns: Operational management, insurance and technical maintenance of the generating plants are entirely NewSun’s responsibility. 

• 100% Digital, Straightforward Sign-up: The transition process is entirely administrative and digital, without inflexible contracts and with a guarantee of continuous electricity supply.

Conclusion 

Structuring an internship programme in your Small or Medium-sized Enterprise is a strategic decision with an exceptionally high return on investment. By creating space for young students’ curiosity, digital fluency and eagerness to learn, your SME not only meets everyday operational needs at an affordable cost, but also develops its own generation of professionals and leaders aligned with the company culture. 

The key to success lies in strict compliance with the guidelines of Law No. 11,788/2008, ensuring that the internship retains its nature as a supervised educational activity, with appropriate working hours, continuous technical support and legal certainty for both parties. When the time comes to offer permanent employment, combine an assessment of individual performance with the maturity of the company’s cash flow to ensure sustainable growth. 

Likewise, applying this innovative mindset to infrastructure management—by adopting NewSun’s clean energy subscription to ensure protection and complete predictability against increases in electricity bills—provides the budgetary stability needed for your company to continue hiring, innovating and leading the market profitably and with a forward-looking vision.
