Either stay where they are, shocked at the cost and risk of looking for a new one and the disruption of actually getting one and needing to move, perhaps both place of work and the home.
Even those who go further and actually start applying for jobs don't usually make much use of all the research that they've done. More jobs are offered and accepted over a pint or during a short conversation in a lift than you would believe possible. That's the usual method of course and that's why moving is so often a disappointment both for those who move and those who hire them. Too much ( a great deal too much) emphasis is placed on the personal contact so that the entire marketplace simply isn't either surveyed or really taken proper note of.
The difficult way is to do all of that work with the databases, the job ads and the newspapers and ignore those beguiling whispers from those you know in the trade. To make up lists, contact all those on them, send in the multiple CVs and travel the countryside for months desperately hunting for that match between your desires and those of a potential employer. The problem with this method is that you can never actually catch up with the marketplace: the process of surveying it takes too long for one individual. If you're working without the benefit of the total industry knowledge, by the time you've selected that small portion of the offers you want to apply for there are more on the market, those you were interested in probably already being filled. So difficult and slightly counter-productive as you never actually quite do get what you're looking for.
The third way is the easy way. Use the skills of the recruitment consultants at Talisman. They already know who is looking for people, they've been given (as the employers are paying them to do this of course) a great deal more information about what or who is being looked for than any advertisement can possibly tell you. It's not just the easy option actually, using experts to do what they are experts in, it's the sensible one.
