I've only worked at places with fixed accrual based on years of service, but I would pose the following thought experiment: 6 weeks is 30 days off 8 weeks is 40 days off Every Friday for a full year is 52 days, but in practice less since there are a few typically Friday holidays. Would a manager be ok with someone having a policy of taking every Friday (or Monday) off for a year? Would they be ok with taking off all but 8 Fridays? This would be acceptable (generally, barring regularly scheduled meetings) in most companies I've seen where people get 8 weeks of vacation due to seniority.
