Occupational Pension Scheme actually refers to certain pension benefits that are paid to a specific trade organization or union. There are several ways in which the benefits can be funded. Some of the ways in which one can build up the fun include safe harbor 401 (k) plan, life insurance, annuities as well as other retirement products. Though there are many ways to build the fund one can structure the pension benefits in two ways only. One is defined benefit and the other is defined contribution. In an occupational pension scheme the employer makes the contribution to the pension fund of an employee which is the major benefit of this pension scheme.
