Narrative:

Autopilot (ap) was off. AC was cleared for the approach to xxr at ZZZ. Pilot monitoring (pm) failed to switch to tower for landing clearance. At approx. 500 feet pilot flying (PF) realized the 'cleared to land' light switch was not on. PF asked pm to contact tower for clearance. Pm had the wrong frequency and could not get clearance before touchdown. There was a departing aircraft from the same runway as we approached the threshold. Since I didn't have communication with the tower I did not execute a missed approach in fear of overtaking the departing aircraft. The runway was clear so I landed. There are many factors that led to this occurrence. 1. Brand new first officer (first officer) (two months on line) with no previous jet or part 135/121 experience. He had no concept of ATC flow in regards to what to look for next. Ex; radio frequencies; short approaches etc; etc; etc. He listened well; responded well to advice and learning but was way behind the aircraft a lot of the time. 2. Communication; first officer was very difficult to hear. He kept the boom mic off to the side of his mouth and talked very lightly. We had several conversations regarding it but he never made the effort to talk louder or move the mic. 3. Duty day. We had a 12 hr duty day with six legs (quick turns) after a fairly short overnight the night before. With a 1 hour tarmac delay we had to fly fast and manage quick turns just to be legal to finish the day's assignment. The crew flew from xa:30 to xj:12 without a break or a chance to get food. If we stopped for food we could have easily timed out. These kind of schedules are ridiculous. Six legs; five of which turn through a main hub.by the end of the day the entire crew was exhausted. Throw in the other two factors and it was a recipe for disaster. In hindsight I'm grateful nothing else happened.

Title: The flight crew of a regional jet landed without a clearance. This was due several factors including flight deck workload; fatigue; and radio management in a busy approach environment.
