1. cannot take a couple of days off, without informing their boss much in advance
2. cannot work on something in their off time, on their own computers without employer claiming ownership of it (I am talking specifically about software here)
3. cannot take a unpaid month off, to travel or just rest, for example without losing their jobs
4. have no hope of receiving pension, decent medical benefits etc
5. have no good way of progressing in their career, without having to play bullshit office politics
6. have no concept of maternal, paternal leave, beyond the token few days which is a joke
and so on...
Yes, it is slavery. Compared to Cameroon, this is much better, cushier, comfortable slavery, but it is still slavery, aka wage slavery. We have been brainwashed so much about work, being a good citizen etc etc, that most of us can't even recognize that we give away the best years of our lives in return for a car, a small house and some money - and this is just the lucky ones, most of us don't get even that.
Both are slavery, just different forms of it. Yes, one of them is much better than the other, but they are both slavery.
Google offers unpaid time off, 12 weeks of maternal and paternal leave (more if you are a birth parent), is generally on the more flexible side of IP rights for a US company, provides decent medical benefits, and has a promo system through committees explicitly to minimize the amount of politicking one needs to do.
You're extremely misinformed on what constitutes actual slavery (especially plantation 18th/19th century slavery), up to the point of being disrespectful of their descendants (not forgetting the victims of current forms of slavery).
If working a cushy tech job is slavery then what would be working at a sand mine in cameroon called ?
