I work for a company that offers matching RRSP contributions up to 4% of salary to the Defined Contribution pension plan. This year I went on maternity leave. As per the company policy, I could contribute to my plan as per the salary last year and they would still match up to 4% while I'm on maternity leave. I paid the company my share and they were supposed to contribute my share and their 4% match on a biweekly basis. But I just found that they messed up and didn't contribute to the plan at all. I reached out to them and they accepted the mistake they made and said they will contribute all the due amount soon. But the issue is that because of their mistake I didn't get the benefit of all the market appreciation that happened this year (the funds are invested in S&P500). I don't know if I should also ask them to pay up all the appreciation I missed because of their fault. I know one can make the argument that if the market had gone down this year, would I have paid them for the decline in value of my investment. What should I do in this situation? TIA

So this is the second this has happened. In a small company of 20 employees. I m new to pensions. (32, F) The first time apparently it was an accounting error and it happened everyone that when our salaries changed the pension had not. So the missing money was paid back in a lump sum. But this time it is just me and its a total of €125 over 4 months that left my paycheck but didn't reach my pension. I ve brought it up various times with finance and the broker. But they dont seem bothered. They make me feel like its such a small amount I am pestering them about. Should I continue trying to sort it out... or any other advice?
