Tramways Union Auckland president Gary Froggatt confirmed that the drivers had defied their negotiators' recommendation to accept the deal, but said the company had upset the apple-cart by introducing controversial new rosters to two of its depots in the midst of the pay dispute.
"That really got the drivers angry,'' he said.
It meant working more weekends and longer shifts, many of which would entail driving to the maximum of 5 hours allowed by law before taking a break.
Mr Froggatt said that of 619 drivers who attended a paid stopwork meeting today - for which a four-hour halt was called to off-peak bus services - 57 per cent voted to reject the company's offer of a 6.55 per cent rise in three instalments over 27 months from their existing hourly rate of $18.75c.
He said they wanted it paid in two lots - as a 75c rise now to $19.50c an hour and a final 50c instalment in July, to $20.
