By 1989, the government's position could be described as higher government charges and reduced government services. Increased taxes and fees on motor vehicle drivers, petrol, water, public transport and child care, as the aforementioned cuts to education took effect, the pay of health workers was frozen, workers' compensation to injured workers was limited (although this was later blocked by the Upper House) and state assets were sold off. A series of strikes on the part of teachers and the growing unpopularity of Education Minister Terry Metherell caused problems for the Greiner government during the latter stages of its first term. In August 1989, the Industrial Commission ruled against the government in determining that class sizes were an industrial issue rather than the sole discretion of the Director-General. The government also cut rail services to the north coast, deeming them commercially unviable, and cut 8,000 State Rail Authority employees in an effort to offset the authority's $1 billion annual debt – however, this left the Pacific Highway as the only land transport link for several major towns, and in October and December 1989, two major crashes on the road, both involving passenger buses, claimed a combined total of 54 deaths and 55 injuries. While Opposition Leader Bob Carr made the link between pressure on roads and withdrawal of the country services, a coroner's report in April 1990 pinned the blame on the Federal Government and its "piecemeal" approach to repairs of the Pacific Highway. The government meanwhile reduced speed limits for heavy vehicles to 90 km/h after the accidents, but a work-to-rule campaign by the Transport Workers Union disrupted Sydney's peak-hour traffic and Greiner overrode the Transport Minister to restore the previous 100 km/h limit in late January 1990.
