I work as consultant in multinational corporation even as I do the same work as regular employees. Recently I've got ill. Nonetheless, I worked with it for a month before going on sick leave but my condition worsened steadily and likewise worsened my work efficiency. So I went to a doctor and due to fever and persistence of symptoms I've got antibiotics for a month. I was aware that long leave from work will be a problem so I asked the doctor for sick leave for a week, but had to extend it for another due to weakness after antibiotics. I informed my superior each time and on this occasion asked how is situation in our department, is there any emergency. Each time I was replied with "it's ok, get cured."
But after I came back to work I noticed that nobody took on my duties while I was absent. More to it, during my absence I was assigned 3 more tasks, one of which became due when I was on leave. Coincidentally, I come back on a week that had planned so many first-priority tasks that upon my return I warned my co-workers that I'll be unable to do lower priority jobs.
Then I was told that if I'm unable to keep pace with my duties then probably I'm unfit for the job. I turned to my superior immediately only to hear that if I'm getting this seriously ill and need so much leave then perhaps they should get a replacement. He stated that while in bed I should work remotely instead of browsing Facebook, because I was given notebook and nobody forbids me from getting overtime hours. If I'm unable to keep up with duties then they can take it over from me easily but it will result in firing me.
As a side note: in our department during last few years we've lost 40% staff while getting 50% more duties. So I'm unwilling to believe it's my fault I can't keep up.
But the question is: given the situation, am I mobbed into submission or should I change my point of view and really submit because it's my superior who is right because it's period of peak workload and we are in crisis time?
