Let's say you're having problems at your job to the extent you've reached tipping point, you can't expect your union to represent you or make representations on your behalf until you've been a member for (circa) 3 months or thereabouts depending on the specifics of each union and even then they couldn't assist you in an issue that predates your membership. In such an instance does it mean you are pretty much on your own unless you can afford a lawyer? Having said that is it possible to still proceed on your own and hope to reach an agreement with your employer before you're looking at a tribunal (given the time and cost it would take to go solo)?
