I'm not sure if you opened another question here because I see in your history.
If a work environment is stressful, that can certainly form the basis for a worker's compensation claim for any stress related time off that has to be taken
However, suing them on the facts you outlined is not an option, because you've described no illegal behavior. I understand that you don't think it is right, but that doesn't create a case. Laws create the ability to sue and while the employer is not breaking the law, you can't sue them for this.
Generalized harassment is not illegal in this court. Unless you can allege that you are being targeted based on race, religion, gender, age, disability or recent medical leave use, you cannot sue them.
If I could tell you differently here I would. I make part of my living suing employers, and if this was the basis for a lawsuit there would be a lot more suits in this country.
Try to stay in this question rather than opening an entirely new one each time you have a follow up. I'll try to close the other one as a duplicate so that we don't get confused here.
