Dan operated a business for many years. Until recently, Eve and Fred both worked for Dan and were described as self-employed and paid tax as self-employed persons. Dan provided all of the computer equipment and software they needed to perform their jobs. Eve was required to work solely on the projects Dan provided, and she had to attend Dan's premises every day from 9am until 5pm. Fred usually worked at home and was allowed to work on other projects. Fred could even arrange for his work for Dan to be done by someone else if he was too busy to do it personally. After three years of employment, and as a result of a downturn in his business sector, Dan has told Eve and Fred that there will be no more work for them and that they will not receive any further payment or compensation from him for their loss of work.
