How much of a $ bump should I ask for when considering a jump into management?

working at a fabrication company in 2001 i was hired at around 17.50 plus company paid my car bill, around $450. Just a 9 to 5er making parts on machines.

Became manager around 2003 and went to about $24 hr plus car was paid off, and was offered 1% of total profit for the year. Didn’t care to much about the 1% profit sharing in fact i made a big stick about it, but when the first year I got a check for about 11k and the next year it was about 24k. After that it leveled back to around 10k a year.

They also matched the profit if we put it into a charles schwab MMA account. I did this for a year or two but decided the money in my bank was better for me at the time.

Becoming a manager was more money, and the job was to make sure production stayed where it was at or better.
2008 laid off when company moved, recieved a bill from company to pay back a weeks pay (around 7 or 8 hundred) Compained that this was unfair, upper management was not pleased with the HR mistake and gave me a 10k severance.

Working at a radio shack a long long time ago, i made around $400 a week. Went to assistant manager and pay went down to $350 and lost all perks like selling spiffs. Also alot more stress involved.

Different companies treat people / workers completely different. Now self employed and glad that I make more and work less.
