Unions are competing both for contracts with employers, but also for employees among other unions. If Union A is demanding but gives good pay, Union B is more laid back but has less reward, and Union C is both demanding and gives poor bay then it will fail as A or B grows.
If there are no competing unions and you're in union C, then you've got no options but to quit or try and topple the union (impossible, effectively).
The actual "competition" wouldn't be among which union the employees joined - rather they would compete to undercut each other on contract negotiation, which would only bolster the employer's hand.
There are good reasons why this is not common practice - but there is also no law preventing multiple unions.
