Interesting this morning on BBC Radio 4 that a moderately sizeable business was pointing out that the additional payroll cost consumes a quarter of their pre-tax profits which are already low in terms of an acceptable return on investment. (Reducing corporation tax as a by product). The business response was all the usual things of cease recruitment, cut back on wage rises, close sites etc, which adversely affects probably the most vulnerable employees, but also, rather interestingly, outsource much more to India etc. They put it as transferring the employment cost out of the UK. This has been doing the rounds on business discussion groups and gathering momentum. It makes sense as then there is no national insurance costs and no employee protection issues at all.
When labour (or any party) gets into a fight with business, there are always unintended consequences. Politicians and civil servants usually have almost no idea how business actually operates.
Incidentally, when people like Jacob say the NHS is not for profit, this is also naive. The NHS buys everything in - all medical supplies, equipment, pharmaceuticals, agency staff and a great deal of scanning (MRI, PET CT etc) and all of these suppliers are very much "for profit" organisations. Because the NHS is not run as a business, procurement attitudes are different to those in commercial enterprise, as those responsible for procurement are not spending their own money. It is not dissimilar to defence procurement. Wasteful but no one cares as the public pays via tax.
