Finance Minister Pravin Gordhan was "on target" in his medium-term budget policy statement on Tuesday, trade union Uasa said.
"Uasa is impressed by the overall tone of the speech," said spokesman André Venter in a statement.
The union welcomed "plans to beef up efforts to curb wasteful and extravagant public expenditure and the shift in spending priorities from welfare to infrastructure and economic growth".
"In addition, the R25 billion package for business support is a clear indication that the minister is serious and convinced that businesses need to be bolstered as the only way to create sustainable jobs," Venter said.
"We are hopeful that the different government departments will heed the call and will ensure that the required competencies are put in place for the correct spending of the budgeted amounts."
Venter said Uasa hoped President Jacob Zuma's sacking of Local Government Minister Sicelo Shiceka and Public Works Minister Gwen Mahlangu-Nkabinde on Monday would set an example.
"We further trust that President Zuma's sacking of two ministers yesterday will spark off a trend to root out corruption and fraud." -Sapa
