Agent666: your story is a very, very important lesson for others to learn from.
Fortunately I too learned this, and very early in my career.
At the start-up I mentioned, there were really two of us doing the lion's share of the testing work which led to sales. Others in the group were more responsible for executing on projects that had already become orders, bringing in sales inquiries that would ultimately need testing, or developing our next generation of technology. So the pressure was on the two of us, and we were working very hard at it. 70 hour weeks were the norm. There was no time for a life in the real world- there was just the job, the commute, and brief down-time that was mostly spent trying to de-stress enough to be able to survive the next day at work. But every day I was in there, there was another test I could do that might make the treatment unit cheaper and hence easier to sell, so it was never an option to just say, "that's good enough". And a lot of salaries were riding on those sales- not just my own.
Sales dried up for a bit, and the company responded by cutting us down to four days per week. A government program kicked in 50% of the reduction in pay resulting from so-called "job sharing".
I woke up and realized a few things:
1) I was working 70 hours but being paid for 40 hours
2) If we made a sale, I was still being paid for 40 hours, and still working 70 to get the next sale
3) If we did somehow turn the company into a success, there was no real up-side for me aside from keeping my job, maybe a pay raise that I likely deserved anyway because I was new in my career and SHOULD have been on the steep slope of pay rises that come with increases in experience, skill and responsibility
4) There were no shares, no bonus, no options - nothing - for me, at least.
I realized I was making a "sweat equity" investment in a company. That investment had a downside- poor salary, and working 70 hour weeks while being paid for 40, and no work-life balance at all. There was no financial up-side for me. There WAS, however, a financial up-side for others more senior- they DID have shares, or bonuses, or something else to motivate them.
So I realized that I'd been given a gift: I'd been cut down from 70 hours to 32 hours per week, in return for 10% pay cut - and I had a day off every week to find another job. I realized something else- I was a workaholic. And 4 days a week cured me of that- I quit workaholism cold turkey and NEVER went back.
My colleague left first- left the industry and engineering entirely, for a time. They put me back on five days per week, and suddenly (since I was the only one left doing those sales-related tests) seemed to express some concern about whether or not I was happy in my position, and what they could do to make me happier. I gave it some thought, and gave them a list- ten different options. A week later, they came back and said they couldn't do any of those things. One month to the day after that, I handed in my notice. I took a job for 20% more base pay which also paid overtime.
Here's the lesson, folks: working for free as an employee is a mug's game. Just don't do it. We're not talking about helping out colleagues during occasional and brief periods of peak workload, spending some unpaid time learning new things or fixing things you've screwed up and feel bad about- we're talking about consistent unpaid overtime. Make sure there's an upside for you personally, or don't do it. The upside can be a meaningful bonus, shares, options, time in lieu which you are actually able to take when you want to, or compensation at regular or overtime rates- or even a top tier base salary- but there has to be something in it for you personally- monetarily- or else you are being scammed- taken advantage of. If you think you're buying brownie points with your boss or management, think again- all your efforts will be accepted, that's a certainty- not necessarily compensated for, acknowledged, remembered or even NOTICED, but they certainly WILL be accepted! If you are bored and want to volunteer, do so for one of the many organizations that are doing good in the world- not for a for-profit company.
