Pros
Great people to work with in a relaxed atmosphere. The safety certification service UL provides is invaluable to the products we use daily! Career opportunities available...if you seek them out.
Cons
1) A Lot of Changes: So many changes in policy and practices over the years that much of the time UL comes full circle to the original process. 2) Promotions are difficult (at least in my experience): Not necessarily a con, but you must specifically develop an action plan with your supervisor during goal setting and specifically indicate that a promotion and subsequent salary increase (don't fall for the old "title change" trick) as a result of meeting or exceeding the goals. 3) Compensation: Payscale.com shows UL as paying 4% below market. If you've been at UL for a while, chances are your salary at your position is probably lower than what a new hire Engineer to UL in the same position would get (Glassdoor is great for updated salary info!). Now if the new hire is getting 4% below market, you can imagine what the long timer is getting. Its because the salary increase are either minisule or far between, but in order to be competitive in the market, the new hire is paid more. More consideration should be given to those who have endured the 'cons" mentioned for so long.
