Based in London, UK. And tape and jointers here?

Hello

Im hoping to get some insight in tape and jointing career specifically in England (even more specifically in London, England)

It seems like a pretty repetitive job doing the same thing everyday and I dont entirely mind that much to be honest but I wanted to know if this is an actual career job where I would get alot of work or is tape and jointing more of an upskill which actual dryliners/ceiling fixers do so they can then tape and joint the walls/ceilings later?

Or is there actually a tape and jointer on site and all they do is tape and jointing all day?

Thanks in advance
