Pros
Not much to share about. Daily work will be less (for day shift employees) and you will be wasting time nonetheless.
Cons
Too much to talk about. 1. 6 days work week. 2. Outdated HR policies. 3. Outdated work culture. 4. Outdated thinking from the management. 5. Emphasis will be on the email subject rather than the purpose of emails. 6. Unless the top management likes you, you will be ever on probation. Which means, you will be on LOP for most of the time. 7. Typical 'Yes Boss' attitude. Management will DEMAND respect. 8. They do not believe in employees. Rather employees are similar to another 'thing' in the office. 9. They will talk about leave policy but will question you even if you are taking off for family issues/functions.
