Tenants must notify their landlord in writing within five business days of finding or suspecting bed bugs. The law itself doesn't say that if you leave because of a concern about bed bugs that your job is guaranteed.You can sue, but, your employer is correct, you will need evidence that the bed bugs came from your job. Your testimony will not be enough. An apartment or house infested with bed bugs is not in safe and sanitary condition. Under OHS, you have the right to refuse unsafe work. You may have a case on your hands and your employer probably wouldn't want to risk an OHS violation. So if you have an infestation, OsaEdoh recommends calling the Philly Tenant Hotline for advice at 2674432500. Philly is ground zero for bed bugs, and the only big city without a policy to help fight them. Local pest educator Michelle Niedermeier wants to change that.
