When does criticism at work become workplace bullying?

“I'm afraid to tell someone their work isn't good enough”

A manager has been putting off a conversation about a report that has arrived late for the third time. The problem is clear; how to address it feels less clear. In Poland, HR advisers have reported managers worrying that any criticism could lead to a bullying allegation, particularly amid changes to employment law. Employers' organisations have raised similar concerns. Searches for phrases such as “is micromanagement bullying?” and “reasonable management action” suggest that the uncertainty extends beyond Poland. The real question is rarely whether managers are allowed to point out poor work. It is how to do so without attacking the person. The law generally permits performance standards and legitimate correction. The challenge is distinguishing those actions from criticism that becomes a pattern of humiliation or harassment.

Employment law protects reasonable feedback, not humiliation

Poland's amended Labour Code, in force since 5 November 2026, expressly excludes conduct that is both justified and expressed appropriately from the definition of workplace bullying, including assessing and criticising someone's work (Article 94³(9)). Both conditions matter; a valid complaint about performance is not a licence to humiliate. Ireland's workplace bullying code likewise distinguishes bullying from ordinary performance management, reasonable corrective action and constructive feedback, even when the feedback is unwelcome (S.I. 674/2020). In Great Britain, Acas gives constant criticism of someone's work as a possible example of bullying (Acas). These are separate national approaches, not one international legal test. German case law generally examines the overall pattern and whether management measures are being used to target someone. French courts may treat management methods themselves as harassment when their effects meet the legal threshold; employers may have to justify challenged measures with objective reasons (Cour de cassation, 07-45.321). Italian case law on mobbing places particular emphasis on a pattern linked by persecutory intent, although other forms of harmful treatment may be actionable. The Czech public defender of rights distinguishes reasonable supervision from bossing, or harassment by a superior. Japanese labour ministry guidance is unusually concrete: repeatedly berating someone loudly in front of colleagues can amount to power harassment, whereas firmly addressing repeated lateness after earlier warnings need not (MHLW, 2020). Across these examples, criticism is not the problem in itself. Its basis, delivery, repetition and context are.

What Polish court judgments reveal about the boundary

Polish case law illustrates the difference. The Supreme Court has treated criticism of virtually everything an employee did, delivered by shouting in front of others, as bullying even though the employer argued that she was especially sensitive to reprimands (Supreme Court, I PK 176/06). Another judgment described aggressive, sweeping, groundless criticism as an affront to dignity (II PK 157/14). By contrast, a court in Białystok did not classify substantively justified feedback as bullying merely because it was phrased inelegantly (III APa 5/16). The Supreme Court has also distinguished justified criticism, conflict between parties on equal terms, an isolated rude remark and poor organisation from a sustained pattern of bullying (I PK 40/11). Formal management tools, including instructions and disciplinary measures, can nonetheless be misused to harass someone (Warsaw Court of Appeal, III APa 25/16). For managers, the questions are practical: Is this about a specific task or the employee's character? Is the claim supported by facts? Is it being said in private? Is one person constantly singled out? A job title or a disciplinary procedure does not settle those questions automatically.

One angry outburst, micromanagement and performance plans

A single angry outburst will not normally satisfy legal definitions that require repeated bullying, including Poland's and Ireland's, but it can still violate dignity and damage a team. Experimental research found that even one rude interaction reduced task performance and willingness to help, affecting both the person targeted and observers (Porath and Erez, 2007). Micromanagement is similarly a matter of degree and context. Excessive monitoring appears among negative behaviours measured in workplace bullying research. A meta-analysis covering 94 samples and more than 23,000 people found no general performance benefit from electronic performance monitoring and linked it to greater stress; transparent, less intrusive approaches were preferable (Ravid et al., 2023). Scrutiny becomes especially concerning when it is imposed selectively or bears no reasonable relation to the work. A performance improvement plan can also be abused. Japanese guidance describes a superior setting targets that are impossible without training, then harshly reprimanding someone for missing them. Assigning a realistic stretch task is different. A defensible plan sets attainable goals, offers the necessary support before assessment, provides time to improve and applies consistent standards.

The same comment can land very differently

What feedback focuses on matters as much as how strongly it is delivered. In a landmark meta-analysis, feedback interventions reduced performance in more than one-third of the effects studied, particularly when they shifted attention away from the task and onto the recipient's sense of self (Kluger and DeNisi, 1996). Destructive criticism that attributes poor results to the person's character can provoke anger and undermine confidence and motivation (Baron, 1988). Email adds another risk: in experiments, readers were poor at detecting intended sarcasm, and in one task they felt 89% confident about interpreting the tone correctly but were right only 63% of the time (Kruger et al., 2005). Cultural context matters too. A cross-national comparison found broad agreement that personal attacks were inappropriate, but judgments about criticism of work varied more (Salin et al., 2019). That is not a reason to stereotype nationalities: a study comparing requests in English, German, Polish and Russian found indirect forms predominated across all four languages, with differences mainly in how speakers softened requests (Ogiermann, 2009). Neurodiversity deserves the same care. In one study, autistic people received less favourable first impressions when viewers watched brief videos than when they saw written transcripts of the same speech (Sasson et al., 2017). A disagreement about “tone” may therefore reflect communication style rather than intent. Evidence about the best feedback format for each autistic or ADHD employee remains limited; asking the individual is wiser than assuming. Nor is there a magic praise-to-criticism ratio: the widely cited 2.9-to-1 figure has been scientifically challenged (Brown et al., 2013).

How to give difficult feedback without crossing the line

A useful starting structure is fact, expectation, reason. Describe the report, not the person; say what needs to change and why. Give sensitive criticism privately rather than performing it for the team. Avoid blanket judgments such as “everything you do is wrong”, and apply standards consistently. When a decision could have serious consequences, such as a reduced bonus, a new work schedule or additional checks, record the work-related rationale. For emotionally charged subjects, a conversation may be clearer than an email; summarise the agreement in writing afterwards. Check understanding rather than asking a perfunctory “Got it?” and explain that the purpose of the feedback is improvement. In a study involving school students, adding an assurance that the teacher held high standards and believed in the student's ability increased willingness to revise work. That result is informative, not a direct trial of management conversations (Yeager et al., 2014). With a performance plan, make targets achievable and offer training before judging the outcome. Small changes in wording help. Instead of “You've messed this up again”, try: “Tuesday's report has three errors in table two. Please send a corrected version by Friday.” Instead of “You're always late”: “You've started after 9:15 three times this month. What's happening, and what can we agree on?” Instead of “Do you understand?”, ask: “How would you summarise what we've agreed?” Firmness and respect can coexist.

Useful criticism is about the work and how to improve it. The more personal, public, relentless or unsupported by facts it becomes, the greater the risk of humiliation and conflict. Good feedback names the issue, sets an expectation and a next step, and leaves room for the employee to respond.

Empatyzer: before a difficult performance conversation

A manager writes to Em: “Anna has submitted a report with the same errors for the second time. I need to be firm, but I want us to work well together. How do I open the conversation?” Em might suggest: “I've found the same three errors in your last two reports. Let's work out why they're recurring and what will help prevent them.” It can then help refine the expectation, deadline and closing question. If both people have Empatyzer profiles, a comparison may add a useful clue: should the manager lead with the facts, explain the wider context or give Anna time to consider her response? The manager arrives prepared, and Anna leaves knowing exactly what needs to improve.
