Thank you. If he has been continuously employed at his place of work for less than 2 years (whether on probation or not) then his employment rights will unfortunately be somewhat limited. Most importantly, he will not be protected against unfair dismissal. This means that his employer can dismiss him for more or less any reason, and without following a fair procedure, as long as their decision is not based on discriminatory grounds (i.e. because of gender, race, religion, age, a disability, sexual orientation, etc.) or because he was trying to assert any of his statutory rights (e.g. requesting paternity leave, etc.).
If the dismissal had nothing to do with any of the above exceptions then he would not be able to challenge it and his only protection would be if he was not paid his contractual notice period, because unless he was dismissed for gross misconduct, he would be entitled to receive his contractual notice period. If he did not have a written contract in place he would be entitled to the minimum statutory notice period of 1 week. His employer would either have to allow him to work that notice period and pay him as normal, or they will have to pay him in lieu of notice.
So when his contract was terminated, assuming he was given the notice he was due, that would have been the end of the matter for him unfortunately. Without protection against unfair dismissal he wold not have been able to challenge the termination and the promises of other work would not have really held much legal ground unless he was made a formal offer of employment, which he accepted.
However, if he as employed on a fixed term contract for 2 years, then the employer could only terminate that if they had the contractual right to do so. It is therefore important to check his contract to see if they had the right to terminate it earlier than the 2 year fixed period If they did not then they could potentially be acting in breach of contract and he could try pursuing them for some compensation for that breach.
This is your basic legal position. I have more detailed advice for you in terms of the steps he needs to follow if he believes there is a reach by the employer, which I wish to discuss so please take a second to leave a positive rating for the service so far (by selecting 3, 4 or 5 stars) and I can continue with that and answer any further questions you may have. Don’t worry, there is no extra cost and leaving a rating will not close the question and we can continue this discussion. Thank you
