This will depend upon the terms of your contract or other agreement in place. If your employer has the right to suspend you, it must follow the procedure set out in the agreement when it exercises that right. As long as it observes its contractual obligations when suspending you, the suspension can proceed as established by the agreement.
Unpaid suspensions will be assessed even more critically, but even a paid suspension can constitute a constructive dismissal where your employer does not have the right to impose it.
