Pension vs 401k: how to choose when starting a new job?
Choosing between a pension and a defined-contribution plan depends heavily on how long you plan to stay at the company and whether you prefer guaranteed lifetime income over market-driven returns. Because pensions typically require meeting a multi-year vesting period before you are entitled to the benefit, job tenure becomes a major gamble if you are unsure whether you will stick around for the long haul.
