[Controller 1] was on LC1; I was Controller In Charge (CIC). [Controller 1] told Aircraft X that he was going to try and [get] him in on 12L when he has been on RWY 12R pattern work. Aircraft X said they were fine on 12R because they were doing single engine landings. [Controller 1] told him that he was going to RWY 12L and cleared him. When Aircraft X was on a tight base; about .5 base; he cleared asked the Cessna [Aircraft Y] if they could do an immediate takeoff. Cessna said yes and was cleared. I told [controller 1] to send Aircraft X around. Got no response. He waited till he was on less than a 1/4 mile final and less than 100 feet up if they could change runways to the south one. Aircraft X did and landed on the south runway. The Cessna was not more than 1000 feet down the runway when Aircraft X landed on the south runway. This is the second time in two days he has ignored me on CIC in a dangerous situation. This is also the same situation where he had changed a plane on short final to a different runway. That time the aircraft went off the runway. He stated that the Front Line Manager pressured him into it. I was up there when this happened and why I said do a go around. He didn't do it just because I said so and he did not learn from the past event. Again this is the 2nd time in two day there has been a dangerous situation due to him.The only recommendation I have is to remove him from the boards until some type of training is complete.
Controller in Charge reported that another Controller operated in an unsafe way by letting an aircraft land when it should have been sent around.
