Can employees who are self-isolating or on sick leave be placed on Flexible Furlough?

Employers had the ability to furlough extremely vulnerable employees who needed to shield.

If your employee is on sick leave or self-isolating as a result of Coronavirus, including as a result of track and trace, they’ll be able to get Statutory Sick Pay, subject to other eligibility conditions applying.

There is no special exemption for them, so they would need to meet the usual requirements to be placed on Flexible Furlough after 1 July 2020. i.e. They had to have been placed on furlough for at least 3 weeks before 1 July. Otherwise, they could not be furloughed.
