you could call your state labor board and complain about unsafe working conditions (bed bugs)
you could also file an anonymous complaint and get others to do so as well

you didn't say what type of hotline it is or what community you serve...it might be possible for them to move you to a different facility while the facility is cleaned...but as for food, etc that is solely on the employees. if they need a larger space for staff...well hopefully mgt can arrange for that..if the need is so great for such a large staff, you would think they would see fit to accommodate everyone, rather then paying others to just stand idly and get paid for not working.

I would complain, but realize that while legally there is whistle blower protection realize that in reality there really isn't. trust me on this.
