‘It’s a good factory, so no one really quits.’

Rumsinah, 44

Role: Zipper operator at PT. Fajarindo Faliman Zipper, which focuses largely on in-house brands

Where: Tangerang, Indonesia

“Most of my co-workers and I are all old-timers,” said Ms. Rumsinah, who has been working at the same factory for 26 years. “It’s a good factory, so no one really quits. There’s seldom any job openings — only if someone retires.”

She is paid about 3.4 million rupiah, or $241, per month, which she said is tight as a single parent. Her son recently finished high school. “He can’t work at my factory because there’s no openings,” she said. “He wants to be a teacher, but we don’t have enough money to send him to go to university.”

Though her job is tiring, “all jobs are tiring,” she said. “At least weekends are off, and the hours are not too bad.”
