Pros
Job security as they usually won't even fire morons that are being overpaid that know little to nothing ,and cause outages due to their incompetence.
Kontras
Having one HR rep for thousands of employees. Only way to get anything taken care of is to complain to the HR bosses boss. In America will pay L1 Indians more than they willing to pay their L3+ Admins. No work life balance what so ever as you will get called all hours of any day for something that could wait till the next business day. They will want you to drop everything you are doing for some report they suddenly want, and then complain when other work you had to drop for it was not done. Have gone through so much turn over in management. Lied to by management on pay issues. Have managers that force you to work OT, and then tell you that you cannot enter the OT on timesheet. Instead they tell you to take "comp time". If you have any issues good luck as most the people who can fix issues are in India, and it will take months to get simple things resolved. Vacation time is pitiful. 10 days a year no matter how long you been with company. Good luck taking vacation days without being called and expected to work during it too. If you are lucky enough to get a raise it won't be much. Even top performing employees get screwed over since all reviews are done on a bell curve.
