I am currently on a 3 week unpaid suspension. Am I obligated to answer phone calls, emails, and texts about issues relating to my job knowledge?

An unpaid suspension could be a constructive dismissal. Whether you need to be answering emails or phone calls will depend on what the employer is doing and the reasons for the suspension. We strongly recommend that you schedule a consultation with one of our lawyers to go over your situation in more details and to provide you with your options going forward.
