Most experienced contractors will have had one or two disagreements with clients over the work they have produced, and struggled to resolve the difficult situation without damaging their working relationship.

Tom Albrighton writes on Freelance Folder that one of the major causes of this is not having a detailed enough brief before the work began.

However, he adds, if a client is unsatisfied with the work the contractor has produced, it is important to get constructive feedback so they know exactly where they have gone wrong and will pay extra attention to the problem area in the future.

Mr Albrighton explains that asking questions about what the client would like to change, what they think is missing from the project and how they would like to proceed, can be immensely helpful.

"You mustn't fall into the trap of responding to what you think they want, or what 'clients like them always want', or any other projection of your own ideas," he warns.

Contractors may have to deal with picky clients for longer in the future, after one expert said that people are now working much later into their lives.

Rachel Krys from Inclusive Employers explained that the decline of final salary pension schemes along with the increasing cost of higher education have sparked this trend.
