Career Development

Attracting and retaining top talent is key to a successful organization. At CLS, we ensure our teams thrive by offering the best possible working conditions, support, and growth opportunities.

CLS works every day to ensure that every employee is in the right place and that their skills are used in the right place at the right time.

CLS has set up an “onboarding” program to support employees from their very first day with the company. During the first few months on the job, employees learn about the company and acquire the “in-house” skills and knowledge they need to run smoothly. Processes and procedures, as well as company life, are just some of the skills that all our resource people will be delighted to pass on to our new team members.

Our onboarding journey provides employees with the tools and knowledge they need to excel in their roles in optimal conditions.
