To the extent it doesn’t overly impact institutional knowledge, etc. hiring/firing should be FIFO, if you want to minimize costs. Hire new people, train them up, fire (some) experienced people that cost more.

Whether that’s a “good” property of the system or not, I suppose depends at some level on how you feel about capitalism. Should a business owner be allowed to fire an employee to maximize their company’s value, and eventually their own income?
