Hardship withdrawals from 401(k)s reach high of 4.8% in 2024. Analysis of 3 million retirement accounts at Vanguard research for 2008-2022 shows higher volatility for hourly paid workers than salaried workers. Hourly paid workers have income swings of 15% compared to salaried and when they leave an employer often take out savings in 401(k)s- 42% with income $50,000 to $75,000 took out their savings compared to 28% in salaried group with same income. Many do so to deal with emergency needs. Thus income volatility hurts workers savings in the hourly sector.
A US law passed in 2022 lets employers automatically enroll employees earning less than $160,000 in emergency savings accounts that they can put in $2500 every year in a Roth type account and withdraw from it penalty and tax free. This is helping some employees avoid touching their 401(k)s.
