My promotion dates were postponed by 1 year as a penalty. What shall I do?

I was my 2. month in the organisation and I sent a document that I was not supposed to send but I didn't know that. Therefore, I was taken a disciplinary action and my promotion dates were postponed by 1 year. So, my coworkers who entered the organisation around the same date as me are going to promote in the future but I would always be 1 year behind them.

We normally are supposed two work in a position for at least 2 years to promote from juniorship to seniorship but now I need to wait for at least 3 years. In the end of my 2. year in the organisation, I think of applying for other companies to be hired as a senior specialist so that I would not have to wait for 1 year more to be senior. Is this a good idea?
