Joining salary exchange is an employee’s choice and therefore an employee can not be forced to opt into a salary exchange (salary sacrifice) scheme.
Using salary exchange together with Auto-Enrolment means that if someone hasn’t signed the agreement they still need to be enrolled and therefore make their contributions as currently.
As an employer, you can have two sets of employees: one set in the scheme without Salary Exchange and contributing normally and the second in the scheme with Salary Exchange where the contributions are all made from the employer.
Some employers automatically include new employees in salary exchange (through their contract of employment) while allowing them to opt out of Salary Exchange if they wish.
