You're crazy. Why would they do that? You're just paranoid. When I first realized my office was bugged I tried to tell someone. No one believed me. No one. Not my family or my friends. There were people at work who thought it was true. Either because they thought they too were bugged or heard of others on campus who had been in the past. What do you do? Hire professional help.
Hired a Private investigator. They can do a bug sweep, tell you what they can legally can and cannot do, and help you to gather hard evidence. Most people are trusting my nature, so it is sometimes unbelievable to them that people could be so evil.
Yes, there is no privacy at work, but audio surveillance was not allowed, and they should not have (but did) go through my personal belongs.
