Non-competition clause in sales: protection against migration or sign of a lack of leadership culture?
Anyone who works in sales, whether in key account management, office sales or management, is responsible for sensitive information: price calculations, market strategies, customer dossiers, internal processes. When a key figure leaves the company, the question quickly arises: How do we protect our business, legally, operationally and culturally?
A frequently chosen path: the non-competition clause.
From a legal point of view, this is regulated in Switzerland by Art. 340 et seq. of the Swiss Code of Obligations. It must:
- be agreed in writing (e.g. in the employment contract or separate appendix)
- relate to the specific field of activity and geographical area
- Be proportionate, in particular in terms of duration (max. 3 years), effect and economic impact
- only apply where there is a legitimate interest of the employer
Such an interest exists if:
- the employee had insight into essential trade secrets
- or had personal customer relationships that could cause considerable damage if used in competition
The following are not protected:
- General market knowledge
- publicly available information
- Personal work experience or soft skills
The blanket sentence “You are not allowed to go to the competition” is not legally sufficient. Nor is it enough to write a non-compete clause into the contract as a mere threatening backdrop. Courts scrutinize strictly in the event of a dispute and often declare clauses invalid or significantly reduce them.
And what does this mean for sales practice?
I recommend a double perspective here:
1. Preventive:
Managers should not rely exclusively on contracts, but on lived loyalty. If you create a loyal culture, you don’t have to be afraid of poaching.
Fluctuation is not a legal problem, but often an emotional one.
2. Strategic:
Where it is legally tenable and makes economic sense (e.g. in the case of exclusive customer contracts, sensitive data or personal trust), a well-formulated non-competition clause can make sense, but always in combination with clear onboarding, offboarding and knowledge assurance processes.
After all, a non-compete clause never provides complete protection and does not replace a clever personnel strategy.
A company that only keeps top performers through contracts has long since lost them on a human level.
Unleash potential – celebrate success.
