Is there a minimum period for which an employee must be back at work before they can be furloughed again?

No. From 1 July 2020, a furloughed employee can work on a flexible, part-time basis for their employer (known as flexible furlough). The employer can claim under the Coronavirus Job Retention Scheme for the hours that the employee does not work and is recorded as being on furlough. There is no restriction on the hours or working pattern an employee can work under a flexible furlough arrangement. Employers are not obliged to bring furloughed employees back to work on a part-time basis from 1 July 2020. For example, they could keep employees on a full furlough, or ask employees to work one day, then go back on full furlough again. The three-week minimum furlough period does not apply to claims for periods beginning on or after 1 July 2020.

Prior to 1 July 2020, an employer could choose to rotate which employees were furloughed, or temporarily bring an employee off furlough, provided that each period of furlough lasted at least three consecutive weeks. There was no minimum length of time that an employee who had previously been furloughed must work before the employer could place them on furlough again.
