Pros
I've worked at three Sinclair stations. Some get millions of dollars of brand new gear, some don't. I've been able to climb my way up and have been promoted within in terms of salary and position. Some stations pay for Emmy submissions so the applicant doesn't have to. The also pay photographers to go to the NPPA workshop.
Cons
The company leans too heavily to the right that it discredits the local journalism that the underpaid broadcast teams produce. Sinclair also requires stations to air "must runs" These are segments that, depending on the piece, every station is required to run nightly or weekly. They have nothing to do with the local market and just go to show the vast loss of touch the corporate choices have on the viewers. One of these is the "Terrorism Alert Desk" which is the opposite of journalism. Sinclair wants every station to look and air exactly the same. Same graphics, same music, same writing style, all a setup for the Sinclair Network, which is coming. Too many stations are in last place in the ratings. Working at Sinclair is pretty standard. It's television news.
