I received short term disability (STD) from Cigna this year. I purchase the STD insurance w/after-tax $$; and my employer does not contribute. This is not taxable income, correct?

i purchase the STD insurance via my weekly pay w/ my employer. the premium is paid w/ after tax $$. My employer does not contribute to the STD insurance premium. I was on leave for 6 weeks this year and receive d the STD insurance payout. Since this insurance was not paid for at all by my employer then i do not claim the payouts as income, correct?
