During a divisive debate at the annual LMCs conference in London, delegates rejected calls for a separate branch of committee for sessional GPs.
The conference also rejected a motion which described the GPC as 'not fit for purpose' in representing salaried GPs.
Dr Rachel McMahon, of Cleveland LMC, said younger GPs felt forced into sessional roles because partners 'controlled' job opportunities.
She said: 'The situation is rotten and it is no surprise that general practice has become less desirable as a career choice.'
The conference praised a report by the GPC working group on sessional representation and its recommendations are to be endorsed in full by the GPC.
