Training salary sacrifice scheme

It seems to me that too few employers are willing to sponsor their employees through qualifications (particularly in these difficult economic times). Perhaps there is an opportunity for a temporary salary sacrifice system to pay for qualifications (perhaps with employers matching employees contributions). The advantage to the employee is that they pay for their qualification with their pre-tax income (i.e. saving tax on the study); the advantage for the employer is that their workforce becomes better qualified (potentially at lower cost); and the advantage to the government/state is that their population becomes better qualified (albeit at the cost of lower income tax take).
