Well, after reading more closely, he wouldn't be a "real" manager. The way I read it, there is a manager (the guy's boss) and him as an assistant manager and those guys do everything at the facility -- help desk, maintenance, servers, etc. It is kind of like when you go to a training class and are surrounded by all these "IT Directors." You then find out that they are the only IT person in a company with 50 people.
Company #1 sucks, do NOT take it. If they can't even give you 2 weeks of PTO to start and have the rest of that horrible benefits package, it isn't worth it.
