Pros
It's a job. I've gotten some okay hands-on training and was able to expand my portfolio a little. An okay place to get (some) resume experience.
The feeling is pretty casual with the freedom to plan your own day and direct your own workload. The people are nice, (apart from Waymon.)
You can ask for the salary you want. Be firm but gentle, do not yield to his attempts to intimidate you, and don't sell yourself short. Know your value and ask for it, do not back down.
If you can dodge Waymon, keep your head down and keep working, it’s an okay place. Not the greatest, but better than some. The good news is your chances of being fired are slim. It’s hard to find people to work here since he keeps chasing them off.
Cons
Waymon occasionally yells and screams at his employees. Sometimes it depends on the person, sometimes it depends on his mood, but at least once a month or so he looses his temper and blows up in a show of impotent dominance. Occurrences range from the most trivial of things not as he expected, to loosing his top over having given conflicting orders and the recipient being confused. He muscles people around saying that he owns the company, so he owns the workers and can do as he pleases, and that those who oppose or question him are wrong. The front desk position catches the blunt of it, no one stays in that position long.
The man has some serious control issues. He dismisses safety regulations, or indeed most all regulations, as trivial and inapplicable. Seems having a small company makes one immune to the rules of larger companies.
The technology is old and outdated, but it works. The laboratory portion has the old feel of being in a high school science lab again. There is almost no room for advancement. One can try to advance the lab, but will have to fight with Waymon every step of the way. (He seems convinced things are just fine as they are, so there's no need to spend money on improvements.)
Because of this, the place is also very disorganized with no data management system apart from FileMaker on Macs. It seems everything must be done the hard, and needlessly complicated, way. Any attempts to fix or update the computer system results in harsh rebuke, hostility, and false accusations. (The man doesn’t know what he’s talking about, and somehow that’s the employee’s fault.)
