The following are the advices given to the foreign employees before they come to India. Twas quite amusing to read them. Some of the gems are below :)
Behaviour at Office
•Supervisors generally prefer that workers come to them for assistance with tasks rather than completing tasks on their own. Indians are very team-oriented and will often work on tasks as a group, not individually, unless they are given explicit instructions.
•Indians may not acknowledge small favors and may not use words like “sorry,” “excuse me,” or “thank you.” This is not a sign of rudeness – quite the opposite … Indians simply may not be accustomed to the use of these polite phrases in the English language. It also indicates that they feel comfortable being “informal” with you, since Indians reserve such acknowledgements for formal situations and for people who are not friends or colleagues.
•Supervisors and workers generally do not socialize outside of the office unless they have known each other for a long time. There are very few project team parties.
•Office privacy, size and location are symbols of status.
•It is advisable to be punctual to appointments. Indian executives prefer late morning or early afternoon appointments.
• Business lunches are preferred to dinners
• Hospitality, such as tea and small talk is a part of conducting business.
•Offices are reserved for management. The person of highest authority or rank has the largest office. Employees generally work in open spaces. Cubicles are limited to a few.
•It is common for employees to decorate their work space with personal items (plants, photos, artwork, etc.).Indians tend to have less expectation than US natives for personal space in public situations where crowds or groups of people are present. On streets or transportation or in similar environments, some jostling or similar contact should be expected
Language Usage
•Never, ever shout to be understood. Speak humbly and remove hyperboles such as “great,” “fine” and “terrific.”
•Avoid word pictures unless they are literally what you mean (e.g., “run that by me again,” “walk me through this,” etc.).
•Do not use “Baseball English” (e.g., “ballpark figure,” touch base,” “pinch-hit,” “home run,” “off the wall,” etc.).
•Avoid negative/positive questions (e.g., “You aren’t coming are you?” might be answered “Yes (I am not coming),” where you might expect a “No.”).
Other 'gyaan'
•Public displays of affection are not acceptable within any of India’s ethnic groups. You should avoid hand holding, hugging, kissing, or any other physical contact other than a handshake while you are in public. However, you may notice a man with his hands around his male friend’s shoulder. This does not indicate sexual preference.
•Never touch an Indian (even Indian children) on the head. The head is considered the holiest part of the body
Vaccinations
The following are immunization recommendations when traveling to India:
• Hepatitis A – Recommended for all travelers
• Hepatitis B – Recommended for all travelers
• Japanese Encephalitis – May be recommended if spending more than 30 days in rural areas
• Rabies – Recommended for expatriates and long term visitors. This is also recommended if
quality medical care may not be available within 24 hours of being bitten or scratched by an animal.
• Typhoid – Recommended for expatriates and long-term visits. Recommended for most travelers.
• Yellow Fever – May be required if coming from an infected or endemic country.
• Polio – Recommended for all travelers
• Updates recommended for all travelers for Tetanus, diphtheria, measles and varicella (chickenpox).
Have you ever realized that we, Indians are actually immune to all these diseases now
I was initially overwhelmed, when I actually spoke to one of them for the first time. However, once you get over the initial jitters, you would realize that they are normal people just like you and me, and the “aura” around the firangees disappeares soon.
