The Dos : Act friendly at all times, even if you're feeling frazzled from all the new information you're trying to process. Be inquisitive with your coworkers. Make small talk about popular television shows or sporting events to spark conversations that are cordial without being too personal. Ask your new coworkers to recommend good places to grab a cup of coffee, buy breakfast, eat lunch and shop. This will help you gain common social ground with colleagues and may also spark an invitation to one of the venues. Give colleagues time to warm up to you gradually. Bring in a tasty treat from home to leave in the lunchroom for all to enjoy. Cupcakes, cookies or fresh fruit are always crowd-pleasers.
