Please assist; we are a manufacturing company with personnel being members of a union. Union membership fees include benefits. One of these benefits is pension fund, calculated on basic remuneration.
Do I calculate on basic income less short time or basic only? Our payroll software, payroll consultants and Union indicate that calc should be based on basic only, however, if short time is ignored and high, net pay might turn out negative due to pension calculated on fixed basic pay. Does TAX regulation indicate the correct procedure?
