Loss of e- is termed as oxidation.
And gain of oxygen is termed as oxidation.

But when O²- is added to a substance it gain e- so it should be reduction?​

Oxidation is the loss of electrons. Reduction is the gain of electrons. Oxidation and reduction always occur together, even though they can be written as separate chemical equations.

Hope that helps..!!
