Sometimes it’s using PTO or sick time (normally I’ve been able to take the time in 2 hour blocks), sometimes I’ve just been able to arrange with my supervisor for an extended lunch break, or just taking an unpaid break during the day and making up the hours later in the day or the week so that I’m not hitting my income or not completing my work.

Also, there’s reasons dentist offices often open early, or work on the weekends. Other necessary services like that may offer extended hours on certain days of the week.
