Does an employer who stops contributions to 401k plan set up by the employer have to pay back monies to the plan.

my employer set up a 401 sar sep plan for the employees with a 1% match the first year with a promise to increase that amount by 1% each year, its come to the employees attention that he stopped matching our deductions with no notice to any of us, i read in the labor laws that this is punishable up to $1000, for over $500, or jail time is this true - Is this your question?
