True, especially in small business. I worked in a manufacturing environment that was sales driven in a 20 day cycle and those last 5 days they nearly made OT mandatory. I didn't need to be there most of the time but they threatened to fire me a few times if I didn't work OT, lol. I got a new job after that BS.Just a piece of advice keep in mind that when you start doing things like working that schedule. Some folks you work for may start to see no problem making things like that a mandatory part of your job. I've been down that road a few times it sucks and I walked away from jobs because of it. Making some extra money every once in awhile is great. Helping out when things are in a tight spot is a great thing to do as well. But sometimes it gets taken for granted you are always open to it no matter what the situation.
Checked my last pay stub. 16 hours of double time and 44 hours of 1.5x this year. I don't like to work OT I do just fine with my wage.
