It sounds like you work for a company that has a wonderful HR dept. If it were me, I would ask them for advice on what they think that you should do. I would also talk to my manager about the situation and ask him/her for advice.
Our company was large enough that we often used a temp. service to cover special projects, while an employee was out on leave, and sometimes on vacation. It would be much cheaper to have an existing employee fill in, due to the short-cut in ramp-up time. The downside is that it is contingent upon scheduling.
There have been other times where supervisors have been able to work with other dept. heads to find and prove a need for a part-time job that didn’t currently exist. Our dept’s. VP was brilliant at doing this. HR has their finger on the pulse of the needs of the company, and I’ve also observed them working their way through some loopholes in order to retain a good employee with a temporary problem.
Let’s say though that none of solutions can work. What about taking a second part-time job? Are there any ways you can reduce current expenditures? When I bought a house, a friend of a friend was in need for a place to live. He was up to his eyeballs in debt. We made an arrangement where he moved in with me, didn’t pay rent, but paid the utilities. We lived in harmony for eight years. Once he finally paid off his debts and saved up some money, he bought his own house.
When I was 30, I moved back in with Mom. My BF and I had just broken up, my father died suddenly three weeks later, and I wasn’t keen on living in Chicago anyway, so I moved home. Three months later, a former co-worker tracked me down and told me about a job that was ideally suited for me. I applied and got the job.
It sounds like you need to focus on the healing of your injury, even if it means making temporary sacrifices. If this leads to signing up for unemployment or medicaid, so be it. That is what they are there for…to temporarily help people out in situations like yours.
Please keep up the diligence in looking for potential solutions. I don’t know you, but I get the feeling that you are a good person and will land on your feet. (Just go gently on the one with the fractured foot and sprained ankle. :) )
