A lot of times employees opinion for Senior management is not taken into consideration.

People are afraid to stick their necks out for others. People will do everything to protect their own reputation. It is generally hard to get promoted. It's not uncommon for it to take 3-4 yrs. to go from a research assistant to a res. asscociate, and another 6 years to get a senior Res. associate title. There are always people who are favor more than others. There can be some very long work days.
