Negotiation of Collective Agreement: Obligation to Invite All Representative Trade Unions

Imagine the scene: in Fontaine, near Grenoble, a service company announces the closure of a site. Employees are worried, trade unions mobilise. But an agreement is signed without all of them having been invited to the negotiating table. Result? A conflict that lasts for years, and ultimately, the court annuls the agreement. I saw this situation in my office in Grenoble: employees discovering that the agreement concerning them was negotiated behind closed doors, without their union having been invited. The question every employer asks: 'Am I obliged to invite all unions, even those without a representative in my establishment?' The answer is clear: yes. And the decision of the Cour de cassation of 8 July 2009 forcefully reminds us of this.

The Facts: A Story Like Many Others

Mr X, an employee of a call centre in Lyon, sees his employer, the company Téléperformance France, initiate a plan to close the site. Management summons the unions to negotiate a company agreement. But the Sud union, although representative at national level, is not invited to the local negotiations. Why? Because it no longer has a union delegate in the Lyon establishment. The agreement is signed without it. Mr X and his union challenge this: they refer the matter to the employment tribunal, then to the court of appeal. The latter upholds the agreement, holding that the Sud union, having no delegate on site, did not need to be invited. The union appeals to the Cour de cassation. The Cour de cassation quashes the judgment: it holds that every representative trade union in the company must be invited, regardless of whether it has a delegate in the establishment concerned. The case is remitted to the Grenoble Court of Appeal for a new judgment.

The Reasoning of the Court — Analysed

The Cour de cassation relies on Article L. 132-2 of the Labour Code (now L. 2232-16) which provides that the negotiation of collective agreements must involve all representative trade union organisations in the company or establishment. In other words, for an agreement to be valid, all trade union organisations that have members and influence in the company must be invited to the negotiating table. It does not matter whether they have a union delegate in the specific place where the negotiation takes place. The decision specifies that the absence of a union delegate in an establishment does not exempt the employer from inviting the union that is representative at company level. In short, the right to participate in collective bargaining is attached to representativeness, not to the presence of a local representative. The judges held that the court of appeal had violated this principle by upholding the agreement. This reasoning confirms previous case law (Soc., 14 November 2007, No. 06-44.972) and reinforces the duty of good faith in negotiations. However, note that this decision only concerns the invitation stage; the validity of the agreement itself also depends on other conditions.

What This Means for You — Practically

For employers: before opening negotiations, you must identify all representative trade unions in your company (at national or branch level) and systematically invite them. If you are negotiating in an establishment, you must invite unions that are representative in the company, even if they have no delegate in that establishment. In Échirolles, a small service company had to revise its agreement after failing to invite a union representative at national level: the agreement was annulled, and employees lost the negotiated benefits for 6 months. For employees and unions: if you believe your union was not invited despite being representative, you can challenge the validity of the agreement before the judicial court. Time limit: generally 5 years from the date of signature of the agreement. For real estate professionals: this decision may affect collective agreements in large condominiums employing staff (caretaker, concierge): any agreement modifying their working conditions must comply with this rule.

Four Tips to Avoid This Type of Dispute

• Before any negotiation, conduct a representativeness audit: list all representative unions in your company or branch, and check their contact details. Do not forget national unions that may have members without a local delegate.
• Systematically invite all identified unions by registered letter with acknowledgement of receipt, at least 15 days before the first meeting. Keep a copy of the invitation.
• If a union does not respond or does not send a representative, do not conclude the agreement without having officially followed up a second time. Mention in the minutes of the meeting that the invitation was sent.
• Document the negotiation: keep a register of attendance and exchanges. In the event of a challenge, you will be able to prove that you followed the procedure.

This decision is part of a line of protective rulings on trade union rights. The Cour de cassation had already held (Soc., 14 November 2007, No. 06-44.972) that representativeness is assessed at company level, not establishment level, for the invitation to negotiate. More recently, the Macron Ordinance of 22 September 2017 amended the rules on representativeness (threshold of 10% of votes), but the principle of inviting all representative unions remains. Another example: the Cour de cassation annulled a procedural agreement because a representative union had not been invited (Soc., 24 January 2018, No. 16-22.077). What few people know is that this obligation also applies to collective redundancy agreements or job protection plans. The trend in the courts is clear: fair negotiation means inclusive negotiation.

What You Absolutely Must Remember

FAQ: Practical Questions

Q: Does a union without a delegate in my establishment have to be invited?
A: Yes, if it is representative in the company. Representativeness is assessed at company level, not establishment level.

Q: What if I forgot to invite a union?
A: You can regularise by organising a new, complete negotiation. If the agreement is already signed, it can be challenged within 5 years.

Q: Can I negotiate with only one union if it is majority?
A: No, you must invite all representative unions, even those that are not majority. Failure to invite vitiates the procedure.

Q: What are the risks of non-compliance?
A: The agreement may be annulled by the court with retroactive effect. You could be ordered to pay damages to the affected unions (several thousand euros).

Q: Does this rule apply to condominium agreements?
A: No, labour law does not apply to condominiums. But if the condominium employs staff, the collective agreement concerning them must comply with this rule.
