As DM, here’s my advice: when starting a new campaign/table, and you’re recruiting your players, be very upfront about a set schedule. “We will meet every Friday night at 9pm provided I have between three and six available players. Anyone joining this table should have this time available on a regular basis to be considered.” And you’ll get through a few years without issues before people’s lives change their schedules too much.
