Narrative:

During a routine flight to ZZZ the PIC had exceeded speeds in excess of 250 knots below 10000 ft. It is also noted by sic on further researching previous flights; that PIC had exceeded the 250 knots below 10000ft speeds to excess of 342 knots at times often at altitudes as low as 3000ft. This was brought to the PIC's attention several times by the sic. The PIC had made several corrections. Several flights were made with the same crew and crew positions. The sic had brought to the attention of the PIC the same speed issues while inflight and during debriefing and to be alert of the speed restrictions and altitudes compliance issues. The PIC responded by stating he was fully aware of such; and had a copy of the FARS with him. It is suggested that the PIC and sic have different flying backgrounds although the PIC has not had any part 121 training and the sic does; this may be a contributing factor to lack of CRM and cockpit communications between the pilots. Since this is a new paring. Both pilots are captains in the aircraft; however the PIC in this case is also the chief pilot for the company; which may be a contributing factor in the sic being reluctant to confront this issue directly with the PIC; due to the fact that the PIC has threatened the sic about his employment with the company. Currently this crew pairing is incompatible to the safety of flight.

Title: LR-60 First Officer described his CRM discussions with his Captain; also the Chief Pilot of the company; about his flights exceeding 250 kts below 10;000 ft. The Captain ignored the objection and at one point flew at 342 kts below 10;000 ft.
