Correction: That's probably because Chekov is the Navigator and Second Officer and therefore is usually chained to the bridge.
Correction: Because, as can be seen throughout this movie (crewmen beaming off the ship to assassinate the Klingon ambassador, then tampering with files to make it look like the Enterprise fired the torpedoes) he's not a very good security officer.
