For the past six weeks I have been temping at a medium-sized lawfirm (just under 100 employees) as a three month contract assistant practice manager/admin position. It was a last minute position as my predecessor is on long-term sick leave. Given my job insecurity, the higher cost of living, etc., I was keen to secure the contract and at the interview said that I was willing to do whatever to help out in the company. I also felt that saying something like that would prove that I was an eager candid it and that it would set me apart from any competitor interviewees. Unfortunately this comment has now transpired to be a poison chalice of sorts. I have been given any and all work. I wasn't actually given a formal contract so there is no formal job description. I seem to be a catchall for all tasks that need to be carried out. Given that I am a temporary employee, permanent employees are in no way helpful to me and I also believe that there is an element that they are worried about their job security and any weakness on my part will only secure their job for the future. It is really been hell. I made an informal complaint to my boss about the sheer workload and how I was being told to do anything and everything and he directly quoted me from the interview saying that you were happy to do whatever was needed to be done and what ever you could. I feel this is unfair. Whilst I may have had a helpful and can-do attitude I feel that that has now been exploited to what feels a lot like slave labour. I work non-stop I don't even have time for a lunch break and I am one of the lowest paid employees there, I am just slightly above the minimum wage. The level of responsibility and workload is in no way proportionate to the pay that I am receiving.
I have two questions that I need advice on.
If I just leave am I liable for anything? I did not receive any kind of contract I was just told that I had the job please come in. I'm aware that if I leave abruptly with no notice I'm not going to be able to secure a reference. As it's just been six weeks I'm willing to take that risk. I'm not particularly concerned about professionalism as frankly they don't seem particularly professional to me either despite being a reputable city law firm.
For future interviews, should I just never say that I'm willing to do whatever is needed to help out. I have always thought that shows a can-do and eager attitude but I have now found that that is something that can get exploited. Would you recommend candidates say a phrase such as that and if not what would be a suitable alternative?
