Can you give an example?
I'm finding it difficult to grasp why, if your role involved a lot of travel, this wasn't taken care of for you (in terms of hotel bookings, flights etc.) by secretarial staff.
Were you left stranded by work in a foreign country with no return flight booked, and were thus forced to walk into a hotel and book a stay? Do you have a policy in place for situations like that were you pay and claim reimbursement? It's a little hard to work out why any situation(s) involving legitimate business needs could lead to something of these proportions.
I could see a situation, for example, where you were on the other side of the country with a group of co-workers for the day, and they decided to hit the town on Friday night. You decided to join them, and being too far away from home would require a hotel. So you book one. On the company. This would be a mistake as it hasn't been approved, otherwise one would have already been arranged. However, in that situation I would also expect return travel to have been arranged prior by the company for the end of your trip. So, in this situation you would have had to had abandoned your arranged return travel in order to claim a hotel stay to go out on the lash... all on the excuse that if it weren't for the company, you wouldn't have been there.
I hope I'm a million miles away from the truth.
One example was how I was invited to attend a dinner event in London to pick up an award at the Grosvenor Hotel. Getting back to Manchester that evening would have been impossible given the distance so I booked a local hotel at the corporate rate.
With regards to the budget it was coming out of, there was meant to be a 'Budget Committee' that had to agree on spend prior to committing but this was never strictly implemented despite it being a requirement of an Executive.
The four people on the Committee, of which I was one would meet and review budget requests and decide collaboratively. As one person in particular - the person who I believe has instigated this whole issue - would routinely self-approve thousands of pounds worth of spend. Whether it be drinks, corporate sponsorship or travel, this person would routinely approve on her own without consulting other members of the committee.
It was on this basis that I believed that (a) as I had never had sight of the travel policy, I didn't know that there was a procedure to follow (b) as we both had an equal position on the budget committee and she was self-approving amounts well into their thousands, I was unaware that my actions were wrong.
Hope I've been able to explain this.
