In 2004, I was taken to dinner and received my partnership offer. The only thing negotiable is wether or not you decide to take the offer. There are too many candidates willing to take the position, regardless of compensation, to make any negotiating worthwhile.
For me the compensation was not worth the job. These were the facts in 2004:
1) I'd make 80% of my topped out driver rate, broken down as 70% salary/30% stock
2) I'd lose 1 week vacation
3) I'd work in the same center, with drivers I'd developed friendships with, and have to regain their trust and respect
4) I could be transferred to any operation in the district at any time
5) If my salary was to be paid by the hour I'd realistically earn 60-70% of my topped out driver rate
6) I'd be expected to work 11-12 hours a day
These were just a few of the major "perks" I was presented-and I was a highly rated candidate, due to my education. Frankly, my wife said she'd have left me had I accepted this offer and the inevitable stress I would bring home again (I had once been a pt supv and earned the opportunity to drive). Paid by the hour, the drivers are the highest paid classification up until the DM level. Sure, management gets stock options, but if every driver that worked a 47.5 to 50 hour week, buys the same $-value in shares and/or contributes to their 401k, they still come out ahead. As a driver I'll have a fabulous nest egg at retirement, I have more vacation time and sick time, and I earn as much now, as my manager, in total compensation. By the end of this contract I'll earn considerably more than a manager. I'm in my 30's, he's 50. That's not to mention feeder guys who clear 120k. Without being too disrespectful to your decision, the only reason you should even consider management is if driving is too hard for you. Not everyone can work in beast mode and hump day in and out, in weather and climate. But, that's why we're a skilled trade and earn the compensation we do. This is why management tries to make our jobs harder than they need to be. "Haters gonna hate."
Now that you got the low down from the "Hater", it is a tough decision. His points are pretty much on except as I offer my observations below.
Yes, you can negotiate ... I have seen new promotees get 5% or more by negotiating. Never saw 10%.
There are very few internal (Drivers) candidates who are willing to take the leap.
The 5,000 for insurance is at your current age. If prescription drugs become an issue as you age, you can easily pay 5K - 10K additional per year. There is no cap limit on management prescriptions but it maxes at $300 per Rx filled.
A center manager total compensation is more like $120K including MIP award.
Supervisors and center manager do not get Stock Options. They get a bonus in the form of stock of which 50% is delayed for 5 years. If the stock goes up in price after 5 years, this can be a nice "bump" in bonus.
Make sure you will get a pension in management ( I don't think you do).
Consider how marketable your bachelor's degree is.
Liberal arts degree equals ZERO, finance and technical degrees equals a plus.
Obviously, as a driver, you are not utilizing the investment in that degree whether for money or for type of career.
The aging and "beast of burden" aspect of the driver job is definitely a consideration but the stress and BS in management takes it's toll as well.
The fact that you are in supervision with UPS will most likely give you better opportunity to get a comparable job outside UPS. Most UPS management people I know that have left (with a degree) make more than they did at UPS.
Drivers typically do not , losing half their pay typically. The UPS Package Driver is not a Skilled Trade as suggested by Hater above. It is an unskilled manual labor job done at a very fast pace to justify the high compensation. If you leave UPS as a driver, your chance of getting job making caomparable is very slim.
Maybe in California or NYC but not in most of America.
2004 was dire period to be moving into management at UPS.
Opportunities will be increasing over the next 5 - 10 years.
Good luck with your choice.
