Well, unfortunately, the Job Retention Scheme' is an expensive way to run a business.
The staff member has to work (or at least be paid for) 1/3rd of their normal hours which the employer pays in full.
Then the Govt goes 50:50 with the employer to 'top up' the employees pay to 77%, so the Employee only gets 77% of their wages, with the employer pays 55% of the wages and the Govt Pays 22%.
The Employer is paying 55% of wages for 33% of the work
The intention is that the business shows commitment to staff retention. However, if they can't afford it, they can't afford.
Sectors that are currently 'closed' are going to be especially hard hit. NO income, but 55% of staff wages. It just doesn't work.
The £1000 staff retention that will be paid next year, is nowhere near enough incentive to keep staff on, that you can't afford. Juggling staff numbers & hours, is sadly, more cost effective.
It's only going to work where businesses can afford it AND want to keep highly skilled staff.
What has been suggested makes sense. It won't affect DH's pay by much (2%) & is far better value for the Employer, which may enable longevity of the business.
Nothing to stop DH looking for another job if he thinks there's a better option out there or going self employed if he thinks that's possible.
