Introduction:
Healthy companies are based on dynamic relationships between productivity, health, and well-being. The Spanish Association Against Cancer is developing the Smoke-Free Spaces in Companies (SFS) project to complement the current anti-tobacco strategy that aims to transform companies into healthy organizations. The objective was to implement an intervention in an agricultural company using SFS as the framework to promote the company’s transformation into a healthy environment based on a proactive approach that seeks to improve the workers’ quality of life.

Material and Methods:
A 15-month sequential change was proposed, including the following steps: • Assessment of tobacco use among workers • Sensitization and awareness campaign • Informative actions • Creation of smoke-free outdoor areas with designated smoking areas Providing tools for those who want to quit (smoking cessation programs) • Complementary actions: promotion of physical activity and mindfulness workshops.. • Total restriction of tobacco consumption within the company (included in the company regulations), provide information to employees and collaborators (suppliers, customers and visitors), and display signs throughout the premises. • Raise awareness about the environmental damage of cigarette butts.

Results:
The 4 company headquarters (Almería, El Ejido, Murcia and Valencia) have been transformed into Smoke-free Spaces, impacting over 400 people. The implementation of the anti-smoking intervention has served as a gateway for the implementation of other types of health promotion interventions. For example, the RZ just move club in one company attracted the participation of 88 employees, increasing physical activity not only inside but also outside the company, by sharing the healthy activities with their relatives.

Conclusions:
The sequential protocol with a long execution period has helped employees accept the change successfully. Being able to count on facilitative alternatives for cessation of habits together with the restrictive measures has led some employees to quit smoking, with a small number of employees who continue to smoke. The complementary actions proposed have led to the creation of a club where physical activity is promoted with such success that its action has even spread outside the company, involving family members.
