My question involves labor and employment law for the state of: California
Recently, I called out sick due to a medical condition. They told me I needed a doctors note, which I went and got. I disclosed my medical issue with my employer due to the possibility of it restricting me to light duty work. The next day I provided the doctors note and informed him that the problem was handled and I had no restrictions. As it turns out, 3 other coworkers also called in sick that day, so my employer was suspicious and irritable about the subject.
We do contract work for a regulated utility provider. We are a private company and we are non-exempt employees. We work with some employees of the regulated utility in the field at least an hour out of our day. Two days after everyone called out, one of those employees approached my crew (myself and one other employee) and that employee of the regulated utility called me on my "excuse" not to work, and said it out loud, in front of my coworker, who had no idea of why I called out. He then called out everyone else who called out, except for my coworker I was working with that day. Obviously, I have strong reason to believe my employer discussed my personal medical information with the employees of the regulated utility, ie; our client, who then shared three of our medical conditions with a coworker of ours, in front of me, out loud. My condition was of a sensitive (and embarrassing nature). Of course I'm not a cry baby, but my employer bends and breaks rules all the time, and I feel that he has gone too far this time.
My question is, what can I do? My coworker already expressed that he doesn't want to rock the boat, and the utility employee is not known for being reliable or truthful, but there's only one way he could have known all our our medical conditions, and that is through our employer. If anyone has any guidance/advice on that topic, it would be much appreciated.
Thanks!
