document: IBM offers a competitive vacation plan to all regular full-time employees and regular IBM employees who work alternative work schedules. All regular full-time IBM employees receive a minimum of 15 days paid vacation each year.  Your vacation time is based on years of service and type of employment. Full time employees: Full-time employees with 0-9 years of service are entitled to a maximum of 15 days of vacation per year. Full-time employees with 10-20 years of service are entitled to a maximum of 20 days of vacation per year. Full-time employees with more than 20 years of service are entitled to a maximum of 25 days days of vacation per year. Full-time employees are eligible for 20 days of vacation in the year of your 10th anniversary with IBM. For example, if your first date of full-time IBM employment was September 1, 1999, you would be eligible for 20 days of vacation beginning in 2009. You may take your full amount of vacation at any time during this year, but your full amount (that is, 20 days), is not earned until the end of the year.
