South Korean media report the Seoul government will order emergency arbitration between Samsung Electronics' union and the company, after talks between the two sides fell through.
This could avert a proposed strike which is to start on Thursday.
Union leader Choi Seung-ho says the union accepted a proposal presented by a government mediator, but the planned 18-day strike would go ahead as there is still one sticking point.
Samsung's management says the union insists on "unacceptable demands" that include the size of bonuses for loss-making units.
The government had said earlier if it decides to intervene, it would be due to the potential damage a strike could inflict on the economy.
An emergency arbitration order would prevent the strike from going ahead for 30 days while the government mediate talks.
