Although employees may accrue more than three days of paid sick leave under the one hour for every 30 hours worked (or under an alternative accrual standard) under an accrual method, the law allows employers to limit an employeeâs use of paid sick leave to 24 hours or three days during a year.
Modern piano keyboards ordinarily have an octave span of 164â165 mm; resulting in the width of black keys averaging 13.7 mm and white keys about 23.5 mm wide at the base, disregarding space between keys. Several reduced-size standards have been proposed and marketed.
Grand pianos are measure by the length from the very front of the keyboard to the farthest end of the piano along the spine, with the lid closed. The smallest Steinway is 5 ft. 1 in.
