That is in a way incorrect, a furlough claim has a minimum period of three weeks, therefore you cannot claim for 6 days then miss one then claim for 4 days etc etc.
It would appear I’m incorrect, apologies.
On 29 May 2020, the Chancellor announced changes to the Scheme.
Existing scheme closure and ‘flexible furlough’
The old Scheme will close to new entrants on 30 June.
From this point onwards, employers will only be able to furlough employees that they have furloughed for a full three week period prior to 30 June.
Employers who want to place new employees on furlough must do so by 10 June so the minimum 3 week period required can be achieved.
From 1 July, flexible furlough can be used.
For example, an employee who works 5 days a week can be brought back to work for 2 days a week. The employer will pay wages for those 2 days as normal. The Scheme will “continue to cover” the employee for the other 3 working days.
