I have been getting a lot of flea bites at work and I have told supervisors and upper management about the issue, but I haven't gotten much more than they're "going to take care of it". I've been bitten over 100 times and I'm allergic to them so I even had to go to urgent care. My question is if I should wait it out or go to HR? Is this considered an unsafe working environment? I love my job but my skin looks terrible and ive been in constant pain for over a week. Thanks in advance!
