three days of coverage

the past two days have been very long and busy. i had to work days on the north route again. seems the north driver has been sick and has just found out she was suffering from asthamatic conditions. she was told often by the boss this past week to go to the doctor. she finally went last night.
i have had to put off an appointment with my diabetic specialist three times to accommodate sick people in the company. i am hoping to be able to set up an appointment next week.
this is getting to be very frustrating. i want to get a better job.
the process of change is long. i wonder if another employer would be convienent.
