Talks between the United National Transport Union (Untu) and Bombela Operating Company, the operator of the Gautrain, have deadlocked.
Untu on Wednesday rejected both offers tabled by Bombela and gave the company a 48-hour notice that their members will embark on a protected strike over wages on Monday if the dispute is not settled.
A contingency plan has been put into place.
Gautrain spokesperson Kesagee Nayager said they would operate a reduced Gautrain train service combined with a bus service.
The company had offered an increase of 7 percent across the board, 50 percent medical aid contribution, plus a collective bonus target of R8,000 per employee per year; or an increase of 8,5 percent across the board, plus a medical aid contribution of 55 percent but without a bonus.
Instead, Untu is demanding a 10 percent increase on the basic salary plus R1,600 for a housing allowance, an increase from R31,84 to R64 per shift on night work, a transport subsidy, plus a medical aid contribution split 55/45 between employer and workers, and a R20,000 incentive bonus per employee per year.
