Could companies stop matching 401k contributions?

I get a "profit sharing" contribution once per year into my 401k. It isn't a match because you don't need to contribute to get the payment. It runs between 4.75 and 5.00% - at least for the last 3 years. The company is making a massive profit these days.

We have a SEPP plan for us "high level" employees. I'm a grunt and am proud of it. The SEPP plan contributes 8% of whatever I contribute. It has a 5 year vesting period so I don't expect to collect any of it. I haven't read the plan literature carefully but their may be a "retirement vesting" clause. The whole point of the SEPP is to discourage me from leaving the company but it won't have any impact when the time comes.

We still have a defined benefit pension plan and a 50/100 match on the first 5% in the 401(k). The parent companies did away with their defined benefit pension plan years ago and every year are expectations that ours will go that way as well.
