If he has been continuously employed at his place of work for less than 2 years then his employment rights will unfortunately be somewhat limited. Most importantly, he will not be protected against unfair dismissal. This means that an employer can dismiss him for more or less any reason, and without following a fair procedure, as long as the decision is not based on a reason which makes a dismissal automatically unfair. These include:
· Discrimination due to a protected characteristic (i.e. because of gender, race, religion, age, disability, sexual orientation, etc.)
· Taking, or trying to take, leave for family reasons including pregnancy, paternity leave, parental leave, adoption leave or leave for dependants
However, if the dismissal had nothing to do with any of the above exceptions, he would not be able to challenge it. In that case his only protection would be if he was dismissed in breach of contract. That would usually happen if he was not paid any contractual notice period due to him (unless he was dismissed for gross misconduct, where no notice would be due). If he did not have a written contract in place he would be entitled to the minimum statutory notice period of 1 week. The employer would either have to allow him to work that notice period and pay him as normal, or they instead have to pay him in lieu of notice, where he is paid for the equivalent of the notice pay but his employment is terminated immediately.
I appreciate this may not be the answer you were hoping for but it is the legal position and I hope that it at least clarifies where you stand?
