Stress, but I suppose this depends on what department you work in. Working in Engineering I had opportunity to be involved in many different parts of the company including software designs, customer facing situations, training courses, tradeshows, and travel to different parts of the country.
Lutron's culture of using contractors to support engineering is a blessing and a curse. Blessing because we can hire and release contractors depending on needs, which protects full time employees from layoffs. A curse because full time employees are constantly retraining new contractors that rotate into the company for a few months to maybe a year. This is a complete waste of time.
Customer support scenarios are great when you're on the receiving end of support, but what employees go through to "talk care of the customer" is painful. Lutron markets "the best" products which are no more immune to software defects that our competitors. Ours just cost more. Working in customer support, be prepared for a tough career. Tech support positions are nearly impossible to get out of which means you're likely spending years on the phones until you can back-filled and moved to something else.
New employees go through great introductions to the company with different classes at "Lutron University", but after that new product training is non-existent leaving you out to dry unless you take time to learn yourself.
Documentation is a joke. Specifications? Yeah right, but I know this is true elsewhere. Still doesn't mean it's right...
No communication among teams. I concluded this is because how busy everyone is, they don't have time to think about it.
What I've learned is that if you work hard take care of the the customer and the company, you'll eventually get assigned more and more tasks until you break. Which is essentially where I am at right now. No breaks at this company.
