That's all of Samsung Electronics' profit and only the chip plant employees are included in that 45000 figure. If they're going to share the entire company's profits, it would be divided among 260k people. And the demand is 15% of profits to go into a bonus pool. This would be more like 42k per person if divided among everyone.

SK Hynix employees had the advantage that they only have the super profitable memory and NAND business. Samsung also makes phones and other shit that brought in way less profit per person, as you don't really get 80% profit margins on most products. So if it's just the chip industry employees getting the chip industry profits, the number could be a lot higher, otherwise the chip industry employees' generated profits are going to subsidize bonuses to everyone else as well and the amount per person will be lower.
