A custom field only appears on an employee's profile if they have been assigned a custom field.
This can be done as you create a custom field. However, if you didn't select to assign it to everyone or you didn't assign it to them as you added the new employee, you can assign them to the custom field retrospectively.
Click your name in top-right corner, then click Settings.
On the General setting menu, click Employee data.
Click Custom fields, then on the relevant custom field, click Eligibility.
Select who you want to assign to this custom field.
If you select Everyone all employees are assigned this custom field, as well as any new employee.
If you choose Specific employees, you can select the relevant employees.
📌TIP: To shorten the list you can use the filter option. You can also Select all or Select none.
The selected employees are now assigned to this custom field. You can how many employees are assigned to a custom field.
To see who exactly is assigned to a custom field, if a number shows, click on it to see a list of employees.
