Since I'll be moving there on a work visa, what happens in the event that I get a better job offer from a different company than I work for? Can I just submit my notice, serve the notice period and then quit and go work for another company? Should I stay with the employer for a specific period of time before I can switch employers?
I ask this because I currently live in Qatar. The employers actively restrict them from quitting and working elsewhere. If one jumps jobs, it is a crime punishable by immediate deportation. What's the law in UK? Can the employers force penalties in case the workforce wants to leave?
