We now know that about 155 workers will be laid off tomorrow at the Newton-based appliance maker Maytag. U-A-W Local President Pat Teed says that’s how many employees were on the layoff list posted in the factory. Teed says the workers have about eight years of seniority and will be eligible for 26 weeks unemployment benefits and can be recalled if production picks up. Early last week Maytag spokeswoman Karen Lynn said the layoffs were coming to reduce production and avoid a large inventory buildup. At that time she did not say how many workers would be laid off. Starting next week, Maytag’s production employee numbers in Newton will drop to one-thousand-275 — about half the number of workers on the job as recently as three years ago.
