Social media has become part of our daily lives, but its use can also have consequences in the workplace. A post on Instagram, TikTok, X or LinkedIn may affect an employer, its clients or the trust that is essential to the employment relationship.
However, not every comment or criticism justifies dismissing an employee. Each case must be assessed on its own merits.
Freedom of expression has its limits
Freedom of expression protects employees’ opinions and criticism in the workplace. However, this right does not extend to insults, threats, false allegations or the disclosure of confidential information.
Where a social media post constitutes a serious breach of the duty of good faith owed under the employment relationship, the Spanish Workers’ Statute allows an employer to impose disciplinary dismissal.
What types of posts may have employment consequences?
Examples include:
- Serious insults or offensive remarks directed at the employer, managers, colleagues or clients
- Disclosure of confidential information or internal company documents
- Unauthorised publication of images of company facilities, products or clients
- Improper use of social media during working hours where it amounts to a breach of employment duties.
Context is also important. An isolated criticism is not equivalent to an offensive post with wide public exposure or one that causes actual harm to the employer. Likewise, the employee’s role and level of responsibility may also be relevant.
Is dismissal always justified?
No. For a disciplinary dismissal to be lawful, the employee’s conduct must amount to a serious and culpable breach of their contractual obligations, and the sanction must be proportionate to the circumstances.
Therefore, an inappropriate social media post does not automatically justify termination of employment. Depending on the specific facts, a less severe disciplinary measure—or no disciplinary action at all—may be appropriate.
Conclusion
Social media is not outside the scope of employment law. While employees retain their right to freedom of expression, they must exercise it in accordance with their contractual duty of good faith and with respect for the rights of others.
Ultimately, a social media post will justify disciplinary dismissal only where its content and consequences amount to a sufficiently serious breach of employment obligations. For this reason, both employers and employees should exercise caution when using social media.
