I am a network /systems administrator for a small IT firm. I have been with the company since its inception, about five years ago. The job is stressful, and the owners both greatly increase the stress with toxic attitudes and personalities. I have stayed at this job because I love the job (outside of the office) and I have developed good relationships with the clients. Now there are two new employees. These two have been falsely reporting to my boss that I have been giving them misleading instructions to fixing issues they cannot figure out for themselves. Is it legal for me to record workplace conversations without notifying coworkers?
