How do you deal with ageism from boss?

Talk: If you can, speak to your boss about how you feel. If you don't feel comfortable doing that or it doesn't help, talk to your boss' supervisor or the hr manager at your company. Keep a written record of what happened -- date, time, who said what. If nothing helps, get a referral to your company's eap (employee assistance program) if it has one, or contact legal aid. Age discrimination is illegal.
