The probationary contract in Brazilian agribusiness (contrato de experiência) is often handled passively: the company hires, the period goes by, and the decision on permanent conversion happens at the last minute, based more on the manager's general impression than on a structured evaluation built up over the 90 days allowed by law.
This approach wastes exactly the purpose of the probationary contract: a period designed to reduce hiring risk through real observation, not just to meet a legal formality before automatically converting almost everyone to permanent status.
Why the last-minute decision is a common mistake
When the evaluation only happens at the end of the 90 days, the manager has little room to act on any problem identified, and the decision becomes a rushed either-or: convert or dismiss, with no real time to change course along the way. A well-run probationary contract in agribusiness uses the legal split into two periods, usually 45 plus 45 days, as an opportunity for a structured mid-point review, not just an automatic renewal formality.
This mid-cycle review makes it possible to give clear feedback on what is working and what needs to improve, giving the employee a real chance to adjust their behavior before the final decision, instead of discovering an uncommunicated problem only on the last day.
Objective criteria that replace general impressions
Relying on a "feeling" about whether the employee "fit in well" invites bias and inconsistency between different managers. Objective criteria, defined even before the contract starts, such as delivering specific tasks, observable quality of work and behavior in typical situations for the role, produce a more defensible and fairer decision than a subjective impression built up informally.
These criteria should reflect what really matters for that specific role, not a generic checklist applied equally to positions of very different nature, from operational execution roles to technical roles involving complex analysis.
How to make good use of the 90-day probationary period
Day 1
Define and communicate the objective evaluation criteria before starting.
Day 45
Hold the formal mid-point review, with clear, documented feedback.
Day 75
Review progress against what was agreed, without waiting for the last day to act.
Day 90
Decide based on accumulated criteria, not on a last-minute impression.
Criteria defined in advance
Establish what will be evaluated before the contract starts, not afterwards.
Mid-point review
Use the legal 45-plus-45-day split as a real checkpoint.
Documented feedback
Record evaluation conversations; do not rely only on the manager's memory.
A timely decision
Do not leave conversion or dismissal to the last possible day.
When doubt persists until the last day
If, even with a mid-point review and clear criteria, the manager is still unsure about conversion on the last day of the contract, that doubt itself is already a relevant signal. Informally extending the relationship or hoping the problem will resolve itself after the employee becomes permanent rarely produces a better result than confronting the doubt directly before the deadline.
This care connects directly to the broader topic discussed in our article on cultural fit versus job fit in agribusiness, since much of the doubt about conversion comes precisely from the difference between adequate technical competence and real compatibility with the team and the role's routine.
Most common mistakes in managing the probationary contract
Converting automatically without evaluating: it wastes the real purpose of the observation period.
Not giving mid-point feedback: it takes away the employee's chance to correct course before the final decision.
Using subjective, inconsistent criteria: it produces different decisions for similar situations, depending only on the manager.
Postponing a difficult decision in the hope of spontaneous improvement: it rarely resolves itself after the employee becomes permanent.
How to communicate a non-conversion respectfully
When the decision is not to convert, the way it is communicated matters as much as the decision itself. A direct conversation, with a specific and constructive reason, treating the person with respect even when delivering difficult news, protects the company's reputation and reduces the risk of negative public reviews that could affect future talent attraction.
Excessive vagueness, in an attempt to soften the moment, usually confuses more than it helps, leaving the person without really understanding what led to the decision and unable to learn from the experience for future opportunities.
What Brazilian law sets out on the probationary period
Article 445 of the CLT (Brazil's Consolidated Labor Laws) sets a 90-day limit for the probationary contract, usually structured in two periods that together cannot exceed this legal ceiling. Exceeding the deadline or renewing it more than once automatically turns the contract into an open-ended employment relationship, regardless of the company's intention, which reinforces the importance of deciding within the available legal window.
In practice, this legal limit works as an invitation to discipline: it forces the company to structure a real evaluation within a defined timeframe, instead of postponing the decision indefinitely while waiting for clarity that may never appear without a deliberate follow-up effort.
How to tell an adaptation problem from a real fit problem
Not every difficulty in the first days means the hire was a mistake. Adapting to a new routine, a different organizational culture and the learning curve of a specific tool are expected and usually resolve with time and proper support. The real warning sign is when the problem persists even after structured support, clear feedback and a reasonable adaptation time, which suggests a deeper incompatibility than just an initial adjustment.
Telling these two scenarios apart requires the manager to have, from the start, a clear expectation of how much adaptation time is reasonable for that specific role, avoiding both the mistake of giving up too early and that of waiting too long for an improvement that is not really coming, a topic related to the one discussed in our article on DISC in agribusiness team management, where understanding the new employee's behavioral profile helps calibrate that expectation more precisely.
Research from SHRM reinforces that well-structured probationary periods, with criteria documented from the start, reduce both the rate of mistaken conversions and the risk of labor disputes related to the final dismissal decision.
The role of onboarding in the quality of the final evaluation
An employee who receives weak onboarding reaches the final evaluation of the probationary contract at a disadvantage that has nothing to do with their real capacity for the role. Without proper integration, basic information about processes and tools, and a clear introduction to the team, it is natural for performance in the first weeks to fall below the person's real potential, distorting any evaluation made during that period.
This reinforces why a well-run probationary contract in agribusiness cannot be evaluated in isolation from the integration process that precedes it, a topic explored in our article on onboarding in the first 90 days in agribusiness. Evaluating performance without considering the quality of the integration received produces an unfair decision, which may cost the company real talent discarded because of a poorly executed welcome process, not because of the employee's genuine inability. Reviewing, alongside the performance evaluation, whether the standard onboarding was actually delivered to that specific employee is a simple step that avoids this kind of attribution error, and it rarely requires more than an objective conversation with the manager responsible for the integration.
Conclusion
The probationary contract in agribusiness fulfills its real purpose when it is managed with objective criteria defined before it starts, a structured mid-point review and a decision made in time, not pushed to the last possible day. Companies that do this reduce mistaken hires converted out of inertia and strengthen the real quality of their permanent workforce.
