It’s what the scheme is for. Our company (20 employees) will continue to trade but it is likely that the workload/income will be greatly reduced, if you do cashflow forecasts this means that if the entire workforce were maintained on a salary during this period there would not be enough work for them to do, the reduced income and continued salary/tax/NI payments would deplete company funds to the point that nobody would have a job at the end of it & it would come to a point the remaining productive workforce would not be able to be paid, so the company would go under.
Also FT working parents (not key workers) can’t work FT with kids at home -or rather not effectively and it isn’t fair to expect them to. Therefore a percentage of the employees will be furloughed in order to make the company viable in the long term.
Using furlough to reduce overheads makes economic sense in that it will mean that the company can keep 20 people employed after the crisis is over - furloughing them isn’t for fun/taking advantage, it’s using the government resources in the way they are intended.
If companies only used it because they ‘aren’t trading‘ rather than because they are, but in a reduced way, it would mean potentially millions of unemployed in the not too distant future and entire industries going under, which in the long term would cost the taxpayer more.
It sounds like you’re issue is more with you having to survive on less money than an issue with the scheme? In our case everyone will be getting 80% of their salary (because most salaries are under 30k), which given that most people’s costs of travel, childcare and no going out etc will mean they can get through this and have a job to come back to which will help a crippled economy more than them becoming unemployed. I’m pleasantly surprised, especially coming from the Tories - it will mean less job loss and (a reduction in at least) mass unemployment. Would you rather be made redundant?
An employer with a sudden drop in income without the furlough scheme then making redundancies would be the only other option. They are basically paying you to do a job, there is no obligation to continue doing that if there is no work for you, even if other areas of the business are continuing or if they have money in the bank (depleting that in the short term to pay people to do nothing makes no sense for a company who wants to survive).
If furlough wasn’t available, then your personal options when made redundant would be UC (if your household income and savings fall below the threshold - which would cost the tax payer more, especially if you continued to be unemployed after this is over) or if you have a partner earning 25k or more or you have 16k in savings then no personal income at all? I know which option is rather go for!
