I would like to know what is the consensus regarding etiquette on contacting coworkers outside work hours, for example in the evening on a work night (Mon-Fri). If one is working collaboratively on a project and is communicating project related information, without which risks the project being completed late or diverted, how should an employee go about the contact? The team is small, with under 10 team members. No company policy explicitly addresses matters such as this. IM is frequently used among members at work.
Several members have remote access to company intranet. Within the team, contact information is available to all with each persons company's email being used.
