Hi there, it does appear that you are most likely going to be classified as self employed. Your rights in terms of protection against unfair dismissal, redundancy pay and minimum notice periods all depend entirely on your employment status. You have to be an employee to be covered under any of these. If you are genuinely self employed, which you most likely will be, you will not have any rights to challenge the termination, to get any redundancy pay or be able to claim unfair or constructive dismissal. It does not matter how long you have worked there unfortunately, if you are self employed then you remain such and your rights are based on that. The only rights as a self employed worker you would have are in relation to notice period. If you have a contractual notice period then you would be entitled to receive that on termination.
However, it is often the case that no written contract exists, or there is no notice clause in it. In such situations, the worker can still expect a 'reasonable' notice period to have their employment terminated. This is because even in the absence of a written contract they will be working under an implied common law contract and to terminate such a contract a reasonable notice period is required. The only exception is if the contract was terminated because of gross misconduct, that is any misconduct serious enough to justify the employment relationship terminating immediately.
What is a reasonable notice period will vary greatly and will depend on the individual circumstances, industry practices, length of employment, frequency of payment, etc. There are far too many variables to consider, which means it is usually impossible to give a precise indication as to what would be reasonable in each case. It is therefore down to the courts to make that decision. The worker can nevertheless raise this issue with the employer and attempt to negotiate a reasonable notice period with them, a period that they will both be happy to accept.
I'm sorry if this is not necessarily the answer you were hoping for, however I do have a duty to be honest and explain the law as it actually stands. This does mean delivering bad news from time to time. I hope you understand and would be happy to provide any further clarification if needed. If you are still satisfied with the level of service you have received I would be grateful if you could please take a second to leave a positive rating by selecting 3, 4 or 5 starts at the top of the page.
