The health benefits are outrageously expensive compared to both my and my significant other's previous jobs. Many perks (pension, home office expenses for those who primarily work out of an office, the retirement payout schedule, and more) have been cut over the last year which continues to impact employees well-being. Furthermore, with the company having a very down year on the market, there has been a sharp increase in the number of layoffs in several business units which has fed into a developing culture of fear and mistrust.
Biggest con that I can think of - last year, GE found a way to literally take a paycheck from American employees at Christmas. The company has a bi-weekly payout schedule for your salary which means twice a year you have a month with three paychecks. GE, in an effort to get in front of changing OT laws, decided to move the last paycheck of the year to the following week. In affect, American employees, who tend to look at the 'third paycheck' month as a bonus of sorts, were left feeling like they were robbed. It still leaves a very sour taste in my mouth.
