Facebook posts, contributory conduct and reinstatement: lessons from DHL v Ignatowicz [2026] EAT 74

Likely to succeed, though not overwhelmingly. The employer had a potentially fair reason in conduct or some other substantial reason terms because the posts were workplace-related, public-facing, upset colleagues, and arguably risked reputational and workplace relationship harm.

However, a Tribunal is likely to scrutinise proportionality and process closely. The employee had a clean disciplinary record, apologised, removed the original post, said they would not repeat the conduct, raised personal mitigation, and said they had not been trained on the social media policy.

The employer also did not require immediate removal when first aware of the post, which may weaken the argument that there was urgent reputational risk.

Although later posts worsened the employee's position, the formal allegation reportedly focused mainly on the original grievance-related post. Reliance on later posts without clear charge particulars could count against procedural fairness.

On these facts, a final written warning may be seen as the more proportionate sanction, especially for the original post. However, the continued posting during the process materially increases the employer's prospects of defending the claim.

Moderate risk to the employer. Summary dismissal without notice will be upheld only if the conduct was sufficiently serious to amount to a repudiatory breach or gross misconduct.

The employer can point to repeated workplace-related posts, references capable of being read as hostile or threatening, upset caused to a manager, and continued posting even after the investigation and appeal process had begun.

Against that, the employee did not always identify the employer directly, said there was no intent to damage reputation, removed the original post, apologised, and there is no clear evidence of actual reputational damage.

Tribunals often distinguish between conduct justifying disciplinary action and conduct serious enough to justify instant dismissal, particularly for one-off or emotionally driven online comments.

On these facts, the employer has a credible gross misconduct case, but if a Tribunal finds the language fell short of a genuine threat and that dismissal was excessive, notice pay may be awarded.

Unlikely, even if unfair dismissal succeeds. The employee may succeed on liability but still struggle to obtain reinstatement or re-engagement.

Trust and confidence appear materially damaged. Multiple posts were made, including posts after dismissal and during the appeal process, criticising managers and suggesting workplace-related content might be reposted if the matter was not resolved.

Tribunals consider practicality, ongoing working relationships, and whether the employee contributed to the breakdown.

Even where dismissal is unfair, reinstatement is less likely where social media conduct has damaged confidence or workplace relations.

A compensatory or basic award is more likely than an order returning the employee to work.

Likely to fail as a standalone discrimination claim. The scenario refers to comments about capitalism, employers, decision-making and wider political issues, but there is no clear evidence that the dismissal was because of a legally protected philosophical or religious belief.

The employee's best point would be that the posts involved personal expression and that dismissal was disproportionate.

However, belief-related claims require careful proof that the belief is legally protected and that the treatment was because of the belief or its manifestation.

Here, the known employer rationale is reputational risk, workplace morale, upset caused to colleagues, and continued posting. That points to objection to the manner, context and impact of the conduct rather than to the belief itself.

Freedom of expression may still be relevant to proportionality and remedy, but without clearer evidence of a protected belief and causal link, this claim is weak.
