Members of the Samsung union are voting on an annual bonus worth the equivalent of several hundred thousand dollars per person after a deal was struck with the firm's bosses to avert a strike, South Korea's state news agency Yonhap reported on Friday.
The vote on a settlement presented by management is to continue until May 27, Yonhap said.
The compromise includes an average pay rise of 6.2% and the distribution of 10.5% of the company's profit to the workforce.
Forecasts suggest this year's bonuses for employees in the semiconductor division could amount to up to 600 million won (about $400,000) per person. The union is considered likely to approve the deal.
Previously, around 48,000 unionized employees at the world's largest producer of memory chips had threatened an 18-day strike. The strike call was prompted by anger at the level of bonus payments to the workforce after the South Korean electronics giant posted record profits amid a boom related to artificial intelligence chips.
Operating profit for the first quarter alone totalled 57.2 trillion won ($38 billion) - about eight times more than a year earlier.
In an internal report, South Korea's central bank estimated that a strike at Samsung could have slowed the country's economic growth this year by 0.5 percentage points.
The US Chamber of Commerce in South Korea also issued a warning saying the strike could disrupt global supply chains and damage South Korea's reputation as a reliable technology and manufacturing hub.
