[2] [P]ermit employers to set fixed periods of 30 minutes or less that sick time must be used in when it exceeds the employer's required minimum increment.... [3] Explicitly prohibit employers from requiring employees to appear in person or provide any document prior to using sick time when the need to use sick time is not foreseeable.... [4] Clarify the calculation of rate of pay of paid sick time for employees paid on a piecework basis."
