Think in terms that a hostile work environment typically must be caused by discriminatory workplace harassment based on color, race, religious belief, national origin, disability, age or gender. Additionally, the harassment typically must be severe, recurring and pervasive. Your sitution, while frustrating, has no discriminatory aspects to it.
According to the North Carolina Office of State Personnel a hostile work environment is: "A hostile work environment is one that both a reasonable person would find hostile or abusive and one that the particular person who is the object of the harassment perceives to be hostile or abusive. Other circumstances, including the frequency of the alleged harassing conduct, its severity, whether it is physically threatening or humiliating, and whether it unreasonably interferes with an employee's work performance must be considered."
I'm not sure who your employer is but this is a good basis to decide if you believe you need further legal assistance.
