If you are the admin of a company account on Factorial and you have already invited the employees to join it means that they can see:
1- Their own employee account in Factorial
2- Their own documentation and personal data (only their own data, not any other employee's data)
3- The calendar in which all the team appears, the confirmed holidays of other employees and the people who are out of the office.
They will never be able to see personal data of other employees, access to the salary nor compensations of other workers. Don't worry, all the data of the employees is safe in Factorial and will stay confidential. Employees will only see what you want them to see and will never be able to access to private data from other people on the team.
