The first thing to bear in mind is that being placed on suspension is not an automatic assumption of guilt and does not amount to disciplinary action. It is there to be used as a precautionary measure whilst an employer investigates any allegations against the employee. Reasons for suspending could be in the case of gross misconduct, breakdown of relationship, risk to an employer's property, their clients or other employees, to preserve evidence or ensure it is not tampered with, avoid potential witnesses being pressured or intimidated, etc.
Any period of suspension should be as short as possible and reviewed on a regular basis. A knee-jerk decision to suspend, without considering whether this is actually necessary, or if it could be avoided, could result in the employer acting in breach of the implied term of trust and confidence. This could prompt the employee to complain to the employer, such as by raising a grievance.
During the period of suspension the employer should conduct a reasonable investigation into the allegations against the employee. If the investigation gathers enough evidence to justify the taking disciplinary action that could be the next step. In that case the employee has the right to be informed in advance of the allegations against them and be given the opportunity to prepare for the hearing.
On the other hand, if the investigation does not find enough evidence to justify a disciplinary, the employer should terminate the suspension immediately and allow the employee to return to work as normal.
The issue, if the employer is considering dismissal, is that if you have been continuously employed at your place of work for less than 2 years then your employment rights will unfortunately be somewhat limited. Most importantly, you will not be protected against unfair dismissal. This means that your employer can dismiss you 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 you were trying to assert any of your statutory rights (e.g. requesting maternity/paternity leave, etc.). I
If the dismissal had nothing to do with any of the above exceptions then you would not be able to challenge it and your only protection would be if you were not paid your contractual notice period, because unless you were dismissed for gross misconduct, you would be entitled to receive your contractual notice period. If you did not have a written contract in place you would be entitled to the minimum statutory notice period of 1 week. Your employer would either have to allow you to work that notice period and pay you as normal, or they will have to pay you in lieu of notice.
If you were not paid your notice period when you were due one, that would amount to wrongful dismissal (which is different to unfair dismissal) and you could make a claim in an employment tribunal to recover the pay for the notice period that you should have been given. There is a 3-month time limit from the date of dismissal to submit the claim.
Hope this clarifies your position? If you could please let me know that would be great, thank you
