I'd believe in 3 months at the most. Wouldn't you think suspending employment would be a more viable option for SME's instead of redundancy?
I think most businesses will look at that first, but if they suspend employment, how does anyone pay wages,. The employee must agree to it and wouldn't be paid, as they aren't unemployed they then can't claim unemployment benefits so would literally have no money coming in.
I work for a business that will be significantly impacted by this, at this stage there isn't a plan for wholesale redundancies for a couple of reasons (not least the cost of redundancy) and will go down other options (deferring costs etc) but when our highest fixed costs are labour and property rents is obvious where most businesses will be looking.
