Training allowances for mine vocational trainers require additional pay, trainee supervision limits, and preservation of more beneficial company schemes. Training allowances for trainers and instructors at Vocational Training Centres serving coal, metalliferous and oil mines must be paid in addition to normal wages. Trainers receive a minimum daily allowance for each trainee under their supervision, with no more than two trainees assigned at one time. Non-regular instructors receive a minimum daily allowance for vocational training, proportionately reducible for part-day lectures. More beneficial company allowance schemes prevail over these minimum standards.
