Teamleader allows you to restrict CRM access for co-workers. To do so, simply navigate to Settings > HR and click on the pencil icon next to a co-worker's name. Do note, however, that this can not be done for admin users.
If this slider is set to "Yes", the corresponding user will only be able to see companies for which he or she is account manager. In addition, your co-worker will only see contacts related to a company for which he or she is account manager.
