Riding the Rails...

Last week I hit the 6 month anniversary of my new job. I was called in to my managers office and received a very good review and feedback. I am really just finding myself settled in and comfortable in this position. I know my job, I know the people, I feel confident with the work.
So this week was looking to be a quiet week. My manager is on holidays, I was caught up on all the pressing tasks so I could just work my way through all the little piles of things that tend to stack up but aren't urgent. Ah yes just going to be a nice quiet routine week. Well it started out that way. So on Tuesday morning I was walking across the main hall checking on the set-up of the buffet tables for an event that would soon be starting when one of the managers asks if she could have a word with me in private. So we head to my office. My mind is racing - omg what did I do or worse - fail to do? I'm clueless, she then notices the panicked look in my eyes and reassures me - Oh it's good - don't worry! Okay so what could it be?
This manger - well she's not one to beat around the bush so she starts right in. The head admin. assistant has handed in her two week notice and they want to promote me into her job. Hmmm okay, So what does this mean? The hours are firm, 8 to 5, with a one hour lunch. I like my 8:30 starts as I can drop the kids off at school. I also like the 30 minute lunch as that's usually all I need to eat (I nearly always brown bag it). The job is more structured than what I currently do. payroll, billings, scheduling meetings, phones, ordering supplies etc...I won't be as involved in the events as I currently am. But as I said it is a promotion - a 5 level promotion so that means a substantial pay increase and full benefits, something I currently don't receive. I would also be working for her - a new manager and yes that's good ( not that there is anything wrong with my current one)!
I do need to think about it. I need to discuss this with family. The managers also have to work out the job posting details and such with the City Manager. So she says go and think about it, discuss it before I reach a decision.
So I talk it over with Alan. I talk it over with the kids (whom it will impact the most). All they were interested in was how much more it would pay. Sure Mom go for it!!! Okay I've got to make a decision.
Wednesday morning I walk into my office (at 8:30) set my stuff down when I get a call to come into the Manager's office. I head over - So have you decided? Yes! Good! So while we wait for all the decisions to come through the City offices I'll be the interim admin in training and I had to start that very minute as payroll had to be processed that morning and that would be my only chance to get trained to do it before I would take over.
So that train I was riding suddenly was switched to another track. I don't expect it to be a smooth journey - I've never been on train ride that was. I just hope it doesn't turn into a runaway train.
