How much can you get out of your employees before they break?

Business Outlook

Pros

The benefits are excellent including a good vacation package. Depending on the group you work in or the manager you work for, there could be flexible work times available.

Cons

There is an extremely high number of middle management positions which can clog up the lines of communication. There seems to be a lack of sharing of information up and down and also sideways. The message handed down from the executive levels is that the employees at the front lines who are working their tails off are all replaceable, so you'd better work harder to keep your job. This is especially true in these difficult economic times.

Pros

The benefits package is pretty decent, and you get a lot of vacation time (4 weeks to start). Also, because they have a lot of turn-over, your job is pretty secure because they don't want to lose you.

Cons

Your four weeks of vacation time includes any sick time. Also, they only have 6 holidays. Your bonus is based on how the business unit performs as a whole, and has no reflection of how hard you work. If your business unit underperforms, you could end up with no bonus. Management tends to point fingers down on their employees when things aren't performing smoothly, passing the blame onto their staff instead of taking responsibility for their bad management. The company also underpays their employees, especially in the Boston area where the medical markeet is extremely competative.
