employees who aren't always on the ball. Part time employees may not WANT to work FT, maybe it's just to supplement their income; maybe it's for fun money; maybe it's because they work a FT outside of the MT business job but want to keep their skills up.
And obviously the part timers WILL have a job if, as most say, MTSOs don't want to pay for benefits, PTO or holiday.
You have no idea why anyone goes part time, don't assume anything, you know what they say about assuming...
